The first is endocytosis dependent pathway which may be either receptor mediated or nonreceptor mediated and the second is based on endocytosis independent pathway which includes diffusion, membrane

fusion, or PDE screening direct pore transport of the extracellular material into the cell [99]. The process of internalization of CNTs depends on several parameters such as the size, length, nature of functional groups, hydrophobicity, and surface chemistry of CNTs [99, 100]. Figure 5 Pathways for the penetration of CNTs into the cell. (a) Nonreceptor mediated endocytosis: (1) membrane that surrounds the drug loaded functionalized CNTs, (2) internalization Inhibitors,research,lifescience,medical of drug loaded CNTs, and (3) release of drug; (b) receptor mediated endocytosis: … Endocytosis

dependent pathway is an energy and temperature dependent transport process which involves engulfing of extracellular materials within a segment of the cell membrane to form a saccule or a vesicle (hence Inhibitors,research,lifescience,medical also called as corpuscular or vesicular transport) which is then pinched off intracellularly into the matrix/cytoplasm of the cell [101]. Furthermore, internalization endocyte formation was shown to be clathrin mediated, caveolin-driven endocytosis, and through macropinocytosis [99]. In case of receptor mediated endocytosis (Figure 5(b)), ligand conjugated-drug loaded CNT binds to the complementary transmembrane receptor Inhibitors,research,lifescience,medical proteins and then enters the cell as receptor-ligand complexes in clathrin coated vesicles. After internalization vesicles are formed which were known as early endosomes and due to drop in pH, the ligand dissociates from the receptor. When the receptors are released, the vesicles carrying the extracellular particle fuses with lysosomes Inhibitors,research,lifescience,medical and thus trigger the release of the drug particle by the action lysozymes on the endosomes and simultaneously the free receptors thus formed are being recycled to the plasma membrane

for conjugating with other ligand Inhibitors,research,lifescience,medical conjugated CNTs [102]. An example from the antiangiogenetic area is the PD184352 (CI-1040) targeting of integrin αvβ3, which are endothelial cell receptors for extracellular matrix proteins possessing the RGD sequence (arginine-glycine-aspartic acid) and are highly expressed on neovascular endothelial cells. Conjugation of RGD peptides to nanovectors can lead to higher levels of cellular internalization and furthermore affect vascular endothelial growth factor receptor-2 (VEGFR-2) signalling due to intrinsic association with this signalling pathway, leading to downregulation of the receptor and finally to reduced angiogenesis. Another example for active targeting based on ligand-receptor interactions relevant to this area of cancer therapeutics is the interaction of folate with its receptors. Folic acid is a vitamin and necessary for the synthesis of nucleotides, the DNA building blocks.

The magnitude and location of these regions of increased WSSG undergo cyclic changes over the cardiac cycle, exposing ECs in these areas to repetitive changes in direction and magnitude of the WSS and WSSG. We believe that these results provide data to guide further experimental studies and understanding of the hemodynamic component of the mutifactorial driving forces behind the progression of carotid buy JSH-23 disease.
C57BL/6 (B6) is the most commonly used mouse strain in neuroscience. Although recently it has become possible to generate gene-targeted mice using embryonic stem (ES) cells derived from B6 mice, most have been made using mouse ES cell lines derived from 129 mouse substrains such

Inhibitors,research,lifescience,medical as 129S6/SvEvTac (W4 cells), 129X1/SvJ (RW-4 cells), and 129S4/SvJae (J1 cells) (Simpson et al. 1997; Auerbach et al. 2000). Following homologous recombination, Inhibitors,research,lifescience,medical 129 ES cells are usually implanted into blastocysts harvested from B6 females to generate chimeric progeny (Brook and Gardner 1997). These chimeras are crossed with B6 mice to determine

germline transmission in the B6 × 129 hybrid F1 generation. Chimeras that show germline transmission may be crossed with 129 inbred mice to maintain the mutation on an isogenic 129 line, while heterozygous F1 hybrids can be intercrossed to generate Inhibitors,research,lifescience,medical F2 hybrid wild-type and mutant mice for experiments or backcrossed with B6 mice for several generations to generate a congenic B6 line that carries the mutation. Highly backcrossed B6 mice are often desirable because their genetic background is nearly Inhibitors,research,lifescience,medical homogeneous and much is known about wild-type

B6 phenotypes. However, since backcrossing takes considerable time and resources, inbred lines may express phenotypes that interfere with certain experiments, and inbred lines often yield fewer pups per litter than hybrid mice, studies are often performed using wild-type and mutant hybrid mice of the F2 generation where the contribution Inhibitors,research,lifescience,medical of DNA from both genetic backgrounds is ~50% in all mice. A supply of experimental F2 hybrids can nearly be maintained by intercrossing heterozygous F1 breeders, which are in turn replenished by crossing 129 inbred mutants with wild-type B6 mice. Besides considerations of time, cost, and litter size, hybrid mice may be more appropriate for studies in which wild-type B6 mice show an extreme phenotype. For example, the genetic background of mice greatly influences their preference and response to ethanol (Bachmanov et al. 1996; Blednov et al. 2005; Yoneyama et al. 2008); B6 mice exhibit a high ethanol preference in many paradigms, including continuous access two-bottle choice and limited access binge drinking (Belknap et al. 1993; Rhodes et al. 2007). Thus, to determine if a mutation increases drinking, it may be best to use B6 × 129 hybrid mice as moderate drinkers to avoid a ceiling effect.

Major depressive disorders (MDDs) and this website bipolar affective disorders (BPADs) are frequently persistent, disabling psychiatric illnesses [Baune et al. 2007; Kessler et al. 2006]. Lifetime prevalence

of MDDs stands at approximately 16% [Kessler et al. 2003], and BPADs at 1–4% [Grant et al. 2005; Merikangas et al. 2007]: although diagnosed by the presence of pathological highs, depressive episodes (so-called bipolar depression) constitute the majority of illness in Inhibitors,research,lifescience,medical BPADs [Lloyd et al. 2011]. Our recent review [Penn and Tracy, 2012] highlighted the limited efficacy of traditional antidepressants and the lack of a robust evidence base to guide the management Inhibitors,research,lifescience,medical of patients with treatment-resistant depression (TRD). There is a considerable need to develop novel and efficacious antidepressants. Hallucinogenic drugs produce alterations in consciousness,

perception, thought and emotion and have been used recreationally and entheogenically for millennia. So-called ‘classical’ psychedelic drugs such as lysergic acid diethylamide (LSD), psilocybin, dimethyltryptamine Inhibitors,research,lifescience,medical (DMT) and mescaline are thought to exert their effects through agonism at the 5-HT2A receptors [Nichols, 2004]. Dissociative hallucinogens including ketamine, phencyclidine (PCP) and dextromethorphan (DXM) act primarily as N-methyl-D-aspartate isothipendyl (NMDA) glutamate (Glu) receptor antagonists [Krystal et al. 1994]. There has been growing interest in the observation that ketamine has a rapid positive effect on depressive symptoms. Ketamine is used in medicine for inducing and maintaining anaesthesia, and illicitly for its hallucinogenic and dissociative effects. The fact that ketamine does not work through the ‘conventional’ antidepressant monoaminergic targets of serotonin and noradrenaline has provoked excitement: understanding its effects could provide novel insights into the pathophysiology of depression and open up a new class of medications.

13,14 However, vocal mobility may be difficult to assess in the presence of a bulky tumor obstructing visualization. Furthermore, differentiation between reduced movement (T2b) and vocal fixation (T3) can be difficult. The other defining criteria for T3 classification also involve a certain extra level of subjectivity and may depend on the type and quality

of imaging performed and radiological interpretation. For example, minor erosion of the inner lamina of thyroid cartilage is notoriously difficult Inhibitors,research,lifescience,medical to diagnose with a high level of accuracy, yet the presence of this may upstage a small glottic cancer from T1 to T3. On the other hand, T3 tumors may include bulky tumors plastered along the whole inner lamina of thyroid cartilage, with many areas suspicious for erosion, but without any definite areas of gross cartilage destruction which would upstage the tumor to T4. It would seem very intuitive that the latter represents a much less favorable Inhibitors,research,lifescience,medical scenario than a smaller tumor with one focally equivocal area. Likewise, paraglottic or pre-epiglottic space involvement may include a spectrum from cases of very early involvement of these spaces diagnosed on the basis of subtle and possibly subjective radiological appearances, which is still easily amenable

Inhibitors,research,lifescience,medical to transoral laser resection, to extensive and bulky involvement, which is not amenable to any form of conservation laryngeal Inhibitors,research,lifescience,medical surgery, and with decreased likelihood of local control with non-surgical treatment. T4 tumors are subdivided into T4a or T4b, with T4b being defined as tumors with encasement of the common carotid artery, invasion of prevertebral fascia, or direct invasion of the superior mediastinum. The importance of the T4b classification is that such tumors

Inhibitors,research,lifescience,medical are usually MAPK inhibitor considered inoperable without leaving grossly positive margins, and thus such cases are generally considered not appropriate for primary surgical treatment. PRESENTATION The majority of glottic cancers present at an early stage, due to the presence of hoarseness as an early symptom, while the poor lymphatic drainage of the glottis means that cervical metastases are Dichloromethane dehalogenase rare with early primary tumors (<5%). Glottic cancers usually reach an advanced stage after involvement of the ventricle, with subsequent invasion of the paraglottic space and extension to the supraglottis. Vocal cord fixation is an ominous sign, which may arise from bulky involvement of the vocal cord and paraglottic space, or involvement of the cricoarytenoid joint. Destruction of thyroid cartilage and extralaryngeal extension is a late sign which upstages the tumor to T4 classification.

Lymph nodes of the colon form four groups: the epicolic, paracolic, intermediate, and preterminal colic nodes. Epicolic nodes are minute nodules on the serosal surface of the colon. Paracolic nodes lie along the medial borders of the ascending, and descending colon as well as along the mesenteric borders of the P505-15 solubility dmso transverse, and sigmoid colon. Intermediate nodes lie along the ileocolic, right colic, middle colic, left colic, sigmoid, and superior rectal arteries (15). Finally, preterminal nodes lie along the main trunks of the superior and inferior mesenteric arteries and drain Inhibitors,research,lifescience,medical into para-aortic nodes at the origin of these vessels. The drainage pattern of the lymphatic fluid from node to node begins with the nodes

closest to the colon and progresses from multiple

nodes through fewer and fewer nodes as the anastomoses between higher order nodes decrease. This process leads to a nomenclature of hierarchical designation for lymph nodes. Consequently, the para-aortic nodes are usually regarded as the highest nodes of the territory which they drain. Within the Inhibitors,research,lifescience,medical nodes at lower levels there is substantial redundancy in colonic coverage by lymphatic drainage possibly explaining the difficulty in determining sentinel lymph nodes as used in other organ resections (15). As such, a radical lymphadenectomy during resection for colorectal cancer requires the removal of the highest possible Inhibitors,research,lifescience,medical lymph nodes draining the area of the colon in which the tumor is located (15). Though Miscusi et al. showed in a small sample size that approximately 34 lymph nodes normally exist within the mesorectum (16), no studies have been performed that attempted to find the average number of lymph nodes present Inhibitors,research,lifescience,medical in the mesocolon. Figure 1 Diagram of the colon and lymphatic drainage. Lymph node Inhibitors,research,lifescience,medical key: right colic (dark green); superior mesenteric (aqua); middle colic (light green); left colic (dark red); sigmoid (purple); inferior mesenteric (orange). Paracolic lymph nodes (red and purple), … Colorectal carcinoma and anatomic sites There is a growing amount of evidence suggesting colon carcinomas of the right and left colon should

be considered distinct entities. A number of differences between the characteristics of right-sided colorectal carcinomas (RCC) and left-sided colorectal carcinomas (LCC) have been repeatedly demonstrated within the literature. Right-sided tumors are commonly Tryptophan synthase exophytic and present with complications of anemia or abdominal pain. In comparison, left-sided tumors more often cause obstructive symptoms. RCC tends to be: grossly more exophytic in appearance, of the mucinous histologic type and cytogenetically diploid, as well as demonstrate higher rates of microsatellite instability. LCCs, on the other hand, usually possess an infiltrative growth pattern, show chromosomal instability and are more often aneuploid (17). Such differences would suggest RCC and LCC might behave differently.

A preliminary diagnosis is often provided, but it should be emphasized that this is only a preliminary interpretation. Final diagnosis involves examination of the whole sample, including cell block and possible ancillary testing. The sample adequacy depends on the nature of the lesion sampled, and the experience of the aspirator – sometimes only two to three needle passes may be adequate to appropriately aspirate the target lesion. The advantages

of rapid on-site evaluation are a decrease in procedure time, less inadequate/non diagnostic specimens and diminished repeat interventional Inhibitors,research,lifescience,medical procedures (11). The assessment should be as confident and accurate as the sample permits. Slide preparation and staining Prepare smears rapidly. This is optimal if smears are prepared by trained professionals. Half of the slides may be stained for immediate assessment, the remainder quickly placed in 95% ethyl alcohol for later Papanicolaou

staining. Needles should be rinsed in liquid medium for cell block preparation. This permits Inhibitors,research,lifescience,medical histologic assessment and special stains to be performed, if necessary. Extra smears may also be saved for possible immunochemistry. Pathologists should use the rapid stain with which they are most confident: (I) Romanowsky stain requires air dried smears – cell size and stromal components are better defined, however nuclear morphology is Inhibitors,research,lifescience,medical limited. (II) Rapid Papanicolaou stain – provides greater nuclear detail, ability to focus through thicker smears and overlapping cell groups. (III) Toluidine Blue stain – This is ultra fast, but requires subsequent destaining and restaining with

a permanent stain. (IV) Hematoxylin and eosin Inhibitors,research,lifescience,medical – Requires rapid fixation and is more time consuming. However many non cytopathology subspecialty trained pathologists are familiar and more comfortable using this staining Inhibitors,research,lifescience,medical method. Cells of the pancreas The pancreas consists predominantly of the exocrine pancreatic acinar and ductal cells, and a smaller endocrine component consisting of the islets of Langerhans and scattered neuroendocrine Kulchitsky cells in the ducts. Exocrine tissue Serous acinar cells These comprise 80% of the cellularity of the normal pancreas. They are pyramidal, polygonal shaped cells of in small cohesive raspberry-like groups. Single serous acinar cells may be seen with aggressive smearing, ABT869 similar to islet cell tumors. There are indistinct cell borders between cells, but margins of a group of cells are well defined. There is abundant cytoplasm containing coarse zymogen granules. The nucleus is eccentric, may be binucleated, small, round, and uniform (about the size of a red blood cell). Bare nuclei are common. Nuclear membranes are smooth, and there is granular, evenly distributed chromatin, with a prominent nucleolus. Excretory ductal cells This is a minor component in aspirates of normal pancreas.

Background:

Natural medicines have been recently considered more reasonable for human use most notably due to their safety and tolerance. HESA-A is a marine-originated herbal medicine with a variety of healing effects. However, its exact biological mechanism is not clear. The present study aimed at the evaluation of the HESA-A antioxidant effect. Methods: Chinese Inhibitors,research,lifescience,medical hamster ovary (CHO) and human NVP-LDE225 ic50 embryonic kidney (HEK293T) cells were treated with different concentrations of HESA-A and H2O2 followed by cell proliferation assays. The antioxidant effect of the HESA-A preparations was evaluated by an antioxidant assay kit. Results: The viability of CHO and HEK293T cells were about 89% following their incubation with 100 and 200 ng/ml HESA-A, respectively for 1.5 hrs. However, when the cells were incubated with concentrations of 300 ng/ml or more,

the cell viability significantly Inhibitors,research,lifescience,medical decreased to 48% compare to the control cells. The cytotoxic effects of H2O2 were observed after 2 hrs of incubation of the HEK293T or CHO cells with 10 mM or 16 mM H2O2, respectively, while in the presence of HESA-A the cytotoxicity was significantly decreased. Antioxidant assay Inhibitors,research,lifescience,medical revealed that HESA-A scavenges free radicals. Conclusion: The findings indicate that HESA-A had cytoprotective effects in vitro, and that such an effect might be due to antioxidant properties. Key Words: HESA-A, reactive oxygen species, hydrogen peroxide Introduction History of medicine reveals that about 60% of anticancer and 75% of anti-infective drugs, which were Inhibitors,research,lifescience,medical approved from 1981-2002, could be traced to natural origins, which are cheaper and perhaps more productive than chemical compounds.1 Most natural compounds

are part of routinely-used traditional medicine, therefore the tolerance and safety of them Inhibitors,research,lifescience,medical are almost better known than those of chemical entities, which are new for human use.2 In addition, a large number of the naturally derived medicinal compounds is originated from micro-organisms and marine organisms that contain remedies against tuberculosis, malaria, cancer, HIV and other diseases.1  HESA-A 17-DMAG (Alvespimycin) HCl is a drug of herbal-marine origin (Wild celery, Cumin and King Prawn) which is obtained based on anecdotal evidence from Persian folk and traditional medicine. HESA-A showed hepatoprotective and anti tumor properties, and have been patented under Iranian authority.3,4 It is composed of organic constituents, mineral elements such as CaO (43.787%), P2O5 (6.63%), Na2O (3.689%), MgO (2.897%), SO3 (2.193%), K2O (1.988%), SiO2 (1.09%), Fe2O3 (0.375%), Al2O3 (0.354%), and trace elements which are known to possess anti-oxidant and potential anti-cancer properties such as vanadium (V), nickel (Ni), titanium (Ti), zinc (Zn), strontium (Sr) and selenium (Se).4-6 This compound appears to be an effective and safe anticancer remedy that may increase survival of end–stage patients, and can be used in some patients.

For symptom assessment, the Edmonton Symptom Assessment Scale (ESAS)

is used [26]. The ESAS is a validated nine-item patient-rated symptom visual analogue scale developed for use in assessing the symptoms of patients receiving palliative care. The single item depression of the ESAS can reliably screen for depression as measured by more in depth instrument [27]. From published lists of frequent symptoms the study team selected 21, a number considered both feasible to be utilized in practice and comprehensive enough [28]. As next step the E-MOSAIC software was developed, piloted and refined with professionals and Inhibitors,research,lifescience,medical patients resulting in the palm-based assessment E-MOSAIC (Figure1). Figure 1 Screenshot from Palm as illustration. The palm-based assessment consists of three elements Inhibitors,research,lifescience,medical (see screenshots in the Appendix), which are filled out by the patient (element P) and the study personnel (elements

G [weight] and M [medication]). Element P Visual-Analogue Scales (VAS) of 1. Nine frequent symptoms from ESAS (pain, fatigue, drowsiness, nausea, anxiety, depression, shortness of breath, loss of appetite, overall well-being); For E-MOSAIC the single symptoms of the original ESAS were translated in German, French and Italian language in an informal back- and forward process, and validated preliminarily. ESAS Inhibitors,research,lifescience,medical is measured by palm in all patients. 2. Up to three optional symptoms; 3. Patients’ Inhibitors,research,lifescience,medical estimated nutritional intake. Element G: 1. Body weight; 2. Karnofsky Performance Status; 3. Weight loss and body height (Body Mass Index calculated automatically). Element M: pre-defined, simplified list for actual medication for: 1. Pain syndromes, including Inhibitors,research,lifescience,medical assessment of MEDD (Morphin Equivalent [oral] Daily Dose); 2. Fatigue syndromes (Methylphenidate, Erythropoietin, transfusions); 3. Anorexia/cachexia syndromes, and for edema (to control for weight changes). After completion of the assessments the palm is put back to the docking station and the data are transferred

within a few seconds from the docking station to the local computer. The source-code of the E-MOSAIC software is copy-protected. The software is study-specific, most but may be used for other purposes.

The lung is the most accepted EHD site managed with surgical resection. In 1944, Blalock reported the first successful resection of pulmonary metastasis from colorectal carcinoma. Subsequently, Thomford in 1965 defined specific criteria for resection of metastatic colorectal disease to the lung (27). Today, resection of pulmonary metastasis is well-established, although the evidence for the effectiveness

of metastasectomy largely comes from retrospective studies (28-35). Similar to surgical management Inhibitors,research,lifescience,medical of all patients with metastatic disease, patient selection is critical in selleck chemicals llc identifying the best candidates for resection. Clinical practice guidelines for the management of patients with pulmonary metastasis have been established (36). Specifically, general recommendations for the surgical resection of pulmonary metastasis include: (I) metastasis are technically resectable with microscopically Inhibitors,research,lifescience,medical negative (R0) margins

(II) general and functional risks are tolerable (III) primary tumor is controlled, and (IV) no extra-thoracic lesions are present (with the exception of hepatic lesions in which complete removal of both hepatic and pulmonary metastasis is feasible) (Table 2). The presence of concomitant clinically positive disease Inhibitors,research,lifescience,medical in the mediastinal or hilar lymph nodes is a strong contraindication to pulmonary metastasectomy, as this is an ominous prognostic factor associated with prohibitively Inhibitors,research,lifescience,medical poor long-term survival (31-34,37,38). Table 2 Selection criteria for pulmonary metastasectomy. Used with permission: Villeneuve PJ, Sundaresan RS. Surgical Management of Colorectal Lung Metastasis. Clin Colon Rectal Surg 22:233-41,2009. Surgical resection for pulmonary metastasis is associated with a reported 5-year survival ranging from 20% to 60% (28-30,32,39). Several factors have been associated with prognosis following surgical resection of pulmonary CRC metastasis. Specifically, high preoperative Inhibitors,research,lifescience,medical carcinoembryonic antigen (CEA) has been shown to be an independent

factor associated with worse long-term survival (40-43). The number of pulmonary lesions is also associated with long-term outcome. Multiple studies have noted that tumor number is an important independent predictor of long-term outcome (43,44). In one of the largest registry studies Sitaxentan examining long-term results of lung metastasectomy among 5206 cases, the reported 5-year survival was 43% for patients with single lesions versus 27% for patients with four or more lesions (45). Another factor that impacts outcome is whether the patient presents with synchronous or metachronous disease, as well as the disease-free interval between resection of the primary tumor and the pulmonary metastasis. Several studies have noted that a disease-free interval of greater than 1 year between the time of the diagnosis of the primary tumor and the pulmonary metastasis was associated with improved outcomes (37,45).

In the authors’ opinion, the response may be related to hypothalamicpituitary axis activation secondary to stress, resulting in a functional impact on the end organ. Similar effects on the gastrointestinal system, in accordance with those previously reported, suggested that this response may be initiated centrally. Although this study did not review pain or urgency, it made an advancing step in understanding the pathophysiology of these complex disorders. Risk Factors of De Novo OAB and Stress Incontinence After Urethral Diverticulectomy The most recognized complications after surgical

removal of urethral Inhibitors,research,lifescience,medical diverticulum are diverticula recurrence, urethrovaginal fistula, and de novo urinary incontinence. The incidence of de novo urinary incontinence is reported in the literature to occur in 1.7% to 20.3% of patients, but only a few research check details papers debate whether it is required to perform a preventive surgery in those patients at risk. In this study, Dr. Young-Ho Kim7 and colleagues from the Department of Urology, SCH Inhibitors,research,lifescience,medical University Bucheon Hospital (Bucheon, South Korea) assessed risk factors related to de novo stress urinary incontinence (SUI) and OAB by retrospective review of past history, and findings of pelvic magnetic resonance (MR) imaging of patients with urethral Inhibitors,research,lifescience,medical diverticulum. The method consisted of reviewing the 28 patients who underwent surgical removal

of urethral diverticulum between 2002 and 2007 regarding medical history, physical examination, pelvic MR imaging, Inhibitors,research,lifescience,medical changes of voiding symptoms (by Bristol female lower urinary tract symptoms), and occurrence of SUI. The authors also analyzed risk factors of OAB and SUI including age, body mass index (BMI), number of deliveries, size and location of diverticulum, and history of pelvic surgery. Mean

age of patients was 38 (range, 20 to 59 years). OAB was present before surgery in 4 patients and occurred afterward in another 5 patients (20.8%). De novo SUI occurred in 4 of 28 patients (14.3%) after surgical procedure- one of them having both SUI and OAB. Age, BMI, number of deliveries, and history of pelvic surgery did not statistically relate to occurrence Inhibitors,research,lifescience,medical of SUI or OAB. The authors found a relationship between diverticulum size and position and de novo SUI or OAB. SUI occurred in 3 and OAB in 5 out of the 7 patients with diverticulum > 3 cm. Among 11 patients with diverticulum located in proximal urethra, SUI occurred in 4 patients and OAB in 5 patients. In patients with urethral diverticulum > 3 cm Thiamine-diphosphate kinase in diameter and located in proximal urethra on pelvic MR imaging, incidence of SUI and OAB was significantly higher. The authors reported that 3 out of 28 patients had a large defect of urethra after removal of urethral diverticulum or weakened periurethral fascia by repeated inflammation and simultaneously underwent Martius labial fat pad interposition. None of them complained about any symptom of SUI or OAB after surgery.
