Abstract
BACKGROUND Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. METHODS The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. RESULTS A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). CONCLUSION Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov).

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Angiosarcoma is a malignant neoplasm of mesenchymal origin arising from vascular endothelium and most commonly involves extremities. Gingival angiosarcoma is a rare sporadic occurring tumor. We report a case of primary angiosarcoma of gingiva along with a review of 31 cases of primary gingival angiosarcoma reported in literature till 2018. A 30-year-old lady presented with recurrent gingival swelling over central mandible. She had no palpable cervical lymphadenopathy. She underwent central marginal mandibulectomy. Final histological analysis with immunohistochemistry was suggestive of the angiosarcoma of the gingiva. She is 50 months postoperative and doing well.

Abstract
Urothelial carcinoma has a varied and wide histological spectrum posing a diagnostic challenge in H&E examination alone. Immunohistochemical markers like GATA-3 along with other appropriate panel of IHC can be used. However, the percentage positivity and its intensity may vary in different variants and grades of primary and metastatic urothelial carcinoma. To observe the GATA-3 expression patterns in all the grades and different variants of primary and metastatic urothelial carcinomas. It is a prospective and retrospective observational study. All the clinically suspected urothelial carcinoma (UC) during January 2016 to December 2017 were included in the study. Depending on the differential diagnosis considered, immunohistochemistry (IHC) markers including CK7, CK20, p63, AMACR, CDX2, and p16 were done to differentiate UC from other primary carcinomas. The tumors confirmed as UC were analyzed further for GATA-3 expression by Chi-square test. The number of UC in the present study was 126 including 122 (bladder in 107, ureter in 7, renal pelvis in 5, and urethra in 3) primary and 4 metastatic UC (3 in lung and 1 in liver). Age of the patients ranged from 29 to 80 (mean 61.28) years with male/female ratio 4:1. GATA-3 showed positivity in 97 (79.5%) primary UC. GATA-3 was positive in all normal urothelium and non-invasive UC (100%), while it was positive in 69/94 (73.4%) invasive UC including variants. GATA-3 was positive in 35/39 LP invasive (89.74%) and 34/55 (61.81%) MP invasive UC. GATA-3 was positive in 39/40 papillary cases (97.5%) and 45/59 (76.27%) cases of non-papillary UC. GATA-3 showed strong expression in all metastatic UC (100%). GATA-3 expression was seen in 101/126 (80.15%) of UC including primary and metastatic carcinomas and hence was a useful marker in diagnosing UC. The GATA-3 positivity decreased from normal urothelium to UC; low-grade UC to high-grade UC; non-invasive to invasive UC; lamina propria invasive to muscle invasive UC; papillary to non-papillary UC.

Abstract
INTRODUCTION The diagnosis of Ewing sarcoma family of tumours (ESFT) is challenging, especially in adults and in extra-skeletal or visceral location. Several morphologic mimics with varied treatment options and prognosis confer diagnostic dilemmas. Application of ancillary diagnostic modalities in surgical pathology in clinical routine has enabled accurate diagnosis of ESFT in bone, soft tissues, and viscera. AIM The study aims to assess the clinicopathological features including molecular test results of ESFT with emphasis on sex, age, and location, especially extra-skeletal soft tissue and visceral location. MATERIAL AND METHODS Data of clinicopathological, molecular tests (wherever performed), diagnosis rendered in 302 ESFT over a decade from our centre were reviewed. Statistical comparison of skeletal and extra-skeletal tumours with reference to age and sex was done using SPSS package. The P value of <.05 was considered significant. RESULTS The cohort included 302 ESFTs with 49% skeletal and 51% extra-skeletal tumours. Thigh was most common site among skeletal tumours; chest wall, paraspinal location, and retroperitoneum among soft tissues (39.4%); and kidney, ovary, and cervix among visceral tumours (11.3%). Fluorescence in situ hybridisation for EWSR1 gene rearrangement was positive in 54 patients and reverse-transcriptase polymerase chain reaction in 19 patients. Predominance of male sex, younger age and location in extremities among skeletal tumours and lack of gender predilection, higher age and axial location in extra-skeletal tumours were noted, which were statistically significant. Molecular tests were performed more frequently in extra-skeletal tumours, especially in visceral tumours to establish the diagnosis. CONCLUSIONS The study showed statistically significant differences in the age, sex, and location between skeletal and extra-skeletal ESFT. The increased percentage of extra-skeletal tumours especially in viscera was attributed to the increased awareness and availability of ancillary techniques.

Abstract
Although sentinel lymph node biopsy (SLNB) has become a standard of care for management of axilla in breast cancer patients, the technique of SLNB is still not well defined. Unlike radioactive sulfur colloid which requires nuclear medicine facilities, methylene blue dye is readily available. The purpose of this study is to validate the use of methylene blue dye alone for SLNB in early breast cancer patients. 60 patients of early breast cancer were randomized to receive either methylene blue alone (Group A-30 patients) or a combination of both methylene blue and radioactive colloid (Group B-30 patients) for detection of sentinel lymph nodes. Sentinel lymph node biopsy was done followed by complete axillary dissection in all patients. In both Groups A and B, sentinel node was identified in all 30 patients, giving identification rate of 100%. In group A, sentinel node was the only positive node in 1 patient, with a false-positive rate of 14.2%. The negative predictive value was 91.3%. The sensitivity of the procedure in predicting further axillary disease was 75% with a specificity of 95.45%. The overall accuracy was 90%. In group B, sentinel node was the only positive node in 2 cases, giving a false-positive rate of 28.7%. The negative predictive value was 95.65%. The sensitivity of the procedure in predicting further axillary disease was 83.33% with a specificity of 91.67%. The overall accuracy was 90%. Although the false-negative rate was slightly higher with methylene blue alone than that using combination (8.6%-4.3%), it was statistically insignificant. Similarly the sensitivity (75%-83.33%), specificity (95.45-91.67%), and negative predictive value (91.3%-95.67%) were also comparable between groups A and B, respectively. Negative predictive value and false-negative rates are comparable, whether blue dye is used alone or a combination of blue dye and radioactive colloid is used. Sentinel lymph node biopsy with blue dye alone is reliable and can be put to clinical practice more widely, even if nuclear medicine facilities are not available in resource constrained centers, so as to reduce long-term morbidity of axillary dissection, with similar oncological outcomes.

Abstract
Neoadjuvant chemotherapy in gastric cancer can treat micro metastatic disease and can increase the resectability rate. The trial was to compare early outcomes after primary surgery versus neoadjuvant chemotherapy followed by surgery in gastric adenocarcinoma. The primary aim of the study was to compare resectability and R0 resection rates in upfront surgery v/s chemotherapy followed by surgery arm. A secondary aim was to see if neoadjuvant chemotherapy is well tolerated or not by comparing postoperative morbidity and mortality. The study consisted of 60 consecutive patients of carcinoma stomach randomized into primary surgery and neoadjuvant chemotherapy followed by surgery arms. Morbidity, pathological status, and mortality data were collected and analyzed. Mean operating time in primary surgery arm was 290 ± 46.5 min, while in NACTarm, it was 316.7 ± 56.6 min, respectively. When postop complications were compared between the arms, it was not significant. Comparing the histopathological report of two groups, there was no significant difference between differentiated, T stage, mean lymph node harvest, R0 resection, PNI, and LVI. Neoadjuvant chemotherapy showed a trend towards improving in the R0 resection rate. There is no increase in postoperative morbidity and mortality with neoadjuvant chemotherapy.

Abstract
BACKGROUND AND OBJECTIVES Fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) have shown good concordance for the detection of echinoderm microtubule-associated protein-like 4 and anaplastic lymphoma kinase (ALK) rearrangement. Since studies reporting FISH/IHC concordance, clinicopathological features, and clinical outcomes of ALK-positive patients from India are lacking, this study was undertaken. MATERIALS AND METHODS This is a retrospective, observational study of patients with adenocarcinoma of the lung on whom ALK test was performed between March 2013 and December 2015. ALK status was assessed in 341 patients by FISH using Vysis ALK Dual Color Break Apart Rearrangement Probe and IHC using ALK D5F3 clone. Clinicopathological features were noted. Patients were managed as per the standard guidelines. Clinical outcomes - response rate (RR) and progression-free survival (PFS) - were measured. RESULTS ALK rearrangement was positive in 37 patients (10.9%). ALK positivity was observed more commonly in younger patients with no predilection for any gender or any specific histological subtype. ALK by IHC was highly sensitive (100%), compared to FISH with concordance rate of 94.4%. Thirty one of thirty seven (31 of 37) patients received therapy of which 3 patients received palliative chemotherapy and 28 patients received tyrosine kinase inhibitors (crizotinib/ceritinib). Overall RR observed was 77.4%, and median PFS had not been reached at a median follow-up of 12.5 months. INTERPRETATION AND CONCLUSIONS We report higher frequency of ALK positivity (10.9%) in patients with adenocarcinoma of the lung. ALK by IHC is more sensitive than FISH for ALK detection with high concordance. These patients had good clinical outcome with TKIs targeting ALK fusion protein.

Abstract
FT-IR and FT-Raman spectra of bis[(E)-anthranyl-9-acrylic]anhydride were recorded and analyzed. The conformational behavior is also investigated. The vibrational wave numbers were calculated using density functional theory (DFT) quantum chemical calculations. The data obtained from wave number calculations are used to assign vibrational bands obtained in Infrared and Raman spectra. Potential energy distribution was done using GAR2PED program. The geometrical parameters are compared with related structures. The stability of the molecule arising from hyper-conjugative interaction and charge delocalization has been analyzed using Natural Bonding Orbital (NBO) analysis. The Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) analysis are used to determine the charge transfer within the molecule. Molecular Electrostatic Potential (MEP) was performed by the DFT method. The calculated first hyperpolarizability of the title compound is comparable with the reported values of similar derivatives and is 4.23 times that of the standard nonlinear optical (NLO) material urea and the title compound and its derivatives are an attractive object for future studies of nonlinear optical properties. To evaluate the in silico antitumor activity of the title compound molecular docking studies were carried out against protein Bcl-xL. The (1)H-NMR spectrum is also reported.

The vibrational wave numbers were computed using DFT quantum chemical calculations. The data obtained from wave number calculations are used to assign vibrational bands obtained in infrared and Raman spectra. Potential energy distribution was done using GAR2PED program. The NH stretching wave number is red shifted by 102 cm(-1) in IR from the computed wave number, which indicates the weakening of the NH bond. The geometrical parameters (DFT) of the title compound are in agreement with the XRD results. NBO analysis, HOMO-LUMO, first hyperpolarizability and molecular electrostatic potential results are also reported. From the MEP map it is evident that the negative electrostatic potential regions are mainly localized over the CN and CF3 groups and are possible sites for electrophilic attack and positive regions are localized around NH group, indicating possible sites for nucleophilic attack. The preliminary docking results suggest that the title compound might exhibit inhibitory activity against GPb and may act as a potential anti-diabetic compound.

Abstract
Eukaryotic translation initiation factor 5A (eIF5A) is a small acidic protein highly conserved from archaea to mammals. eIF5A is the only protein which undergoes a unique lysine residue modification to hypusine. Hypusinylation is important for the function of eIF5A which is reported to be essential for cell viability. eIF5A promotes formation of the first peptide bond at the onset of protein synthesis. However, its function in Leishmania donovani is unclear. The present study focuses on the characterization and localization of L. donovani eIF5A protein. The eIF5A gene contains an ORF of 501×bp encoding 166 amino acid residues with a predicted molecular mass and isoelectric point of 17.8 kDa and 4.83 respectively. A phylogenetic tree analysis revealed its close proximity to trypanosomes however it is distantly located from Trichomonas vaginalis and Plasmodium falciparum. The L. donovani eIF5A was expressed as a 6× His tagged protein whose identity was confirmed by western blot and MALDI. Biophysical investigation by CD revealed the predominant presence of 49% β sheet structure which correlated well with secondary structure prediction. To gain insight into the role of eIF5A in L. donovani, we investigated the subcellular distribution of eIF5A. A GFP-fusion of L. donovani eIF5A was found to be localized in cytoplasm as confirmed by subcellular fractionation. Our studies indicated that eIF5A is primarily localized to cytoplasm and is undetectable in nuclear fraction. The homology model of eIF5A of L. donovani was built and the resulting model showed acceptable Ramachandran statistics. The model is reliable and can be used to study eIF5A binding with its effector molecules.

Abstract
FT-IR and FT-Raman spectra of 2-(benzylsulfanyl)-3,5-dinitrobenzoic acid were recorded and analyzed. SERS spectra were recorded in silver colloid, silver electrode and silver substrate. The vibrational wavenumbers were computed using HF and DFT quantum chemical calculation methods. The data obtained from wavenumber calculations are used to assign vibrational bands obtained in infrared and Raman spectra as well as in SERS of the studied molecule. Potential energy distribution was done using GAR2PED program. The geometrical parameters of the title compound are in agreement with the reported similar derivatives. The presence of phenyl ring modes in the SERS spectra suggests a tilted orientation with respect to the metal surface in all cases. In all the three SERS spectra the NO2 moiety shows an enhancement, which indicates the interaction with the metal surface. The first hyperpolarizability is high and the title compound is an attractive object for future studies of nonlinear optics.

Abstract
FT-IR, FT-Raman and surface-enhanced Raman scattering spectra of 5-ethylsulphonyl-2-(o-chlorobenzyl)benzoxazole were recorded and analyzed. The vibrational wavenumbers were examined theoretically using the Gaussian09 set of quantum chemistry codes, and the normal modes were assigned by potential energy distribution calculations. The presence of CH(2), SO(2) and CH(3) modes in the SERS spectrum indicates the nearness of the methyl group to the metal surface which affects the orientation and metal molecule interaction. The synthesis, NMR spectra and antibacterial properties are reported. The title compound shows more inhibitory effect against Pseudomonas aeruginosa than ampicillin and found to be more potent against Klebsiella pneumoniae and drug-resistant Bacillus subtilis than the other microorganisms. A computation of the first hyperpolarizability indicates that the compound may be a good candidate as a NLO material. The RMS errors of the observed Raman and IR bands are found to be 30.93, 29.77 for HF and 9.57, 6.75 for DFT methods, respectively.

Abstract
Fourier-transform (FT)-Raman and FT-infrared spectrum of 4-(3-bromopropyl)-4-azatricyclo [5.2.2.0(2,6)]undecane-3,5,8-trione were recorded and analyzed. The vibrational wavenumbers were examined theoretically using the Gaussian03 set of quantum chemistry codes, and the normal modes were assigned by potential energy distribution (PED) calculations. The first hyperpolarizability, predicted infrared intensities and Raman activities are reported. The calculated first hyperpolarizability is comparable with reported values of similar structures which makes this compound an attractive object for future studies of nonlinear optics. The calculated first hyperpolarizability was found to be very high and it is due to the pi-electron cloud movement from donor to acceptor which makes the molecule highly polarized and the intermolecular charge transfer interaction which is justified by the FT-IR spectrum due to the presence of strong broad bands in the region 2873-2000cm(-1). Optimized geometrical parameters of the compound are in agreement with similar reported structures.

Abstract
AIM OF THE STUDY The tubers of Euphorbia fusiformis Buch.-Ham.ex D.Don (Euphorbiaceae) are traditionally used in India by the Malayali tribes of Chitteri hills, Eastern Ghats, Tamil Nadu to treat liver disorders. The objective of the present study was to assess the hepatoprotective potential and biosafety of Euphorbia fusiformis tuber upon administration thereby justifying the traditional claims. MATERIALS AND METHODS The hepatoprotective potential of the ethanol extract of Euphorbia fusiformis tuber against rifampicin induced hepatic damage was investigated in Wistar albino rats. The acute and subchronic toxicity were assessed in mice and rats, respectively. RESULTS The ethanol extract of tubers (250 mg/kg p.o.) showed remarkable hepatoprotective effect against rifampicin induced hepatic damage in Wistar albino rats. The degree of protection was measured using the biochemical parameters serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), gamma glutamyl transpeptidase (GGTP), alkaline phosphatase (ALP), total bilirubin and total protein. Treatment with ethanolic extract prior to the administration of rifampicin significantly (P<0.05 to P<0.001) restored the elevated levels of the said parameters on a par with the control group. The single dose LD(50) was found to be 10,000 mg/kg bw when administered orally in mice. Subchronic toxicity studies in rats with oral doses of 125, 250 and 500 mg/kg exhibited no significant changes in body weight gain, general behavior, hematological and biochemical parameters. The histological profile of liver and kidney also indicated the non-toxic nature of this drug. CONCLUSION The ethanol extract of Euphorbia fusiformis tubers may have potential therapeutic value in the treatment of liver disorders and is safer to use even at higher doses when taken orally.

Abstract
The FT-IR and FT-Raman spectra of 2-phenoxymethylbenzothiazole were recorded and analyzed. The surface enhanced Raman scattering (SERS) spectrum was recorded in a silver colloid. The vibrational wavenumbers of the compound have been computed using the Hartree-Fock/6-31G* basis and compared with the experimental values. The appearance of the Ag-O stretching mode at 237cm(-1) in the SERS spectrum along with theoretically calculated atomic charge density, leads us to suggest that the molecule is adsorbed through the oxygen atom with the molecular plane tilted on the colloidal silver surface. The direction of charge transfer contribution to SERS has been discussed from the frontier orbital theory.

Abstract
Ethanol extract of Clausena dentata (Willd.) M. Roem (Rutaceae) was evaluated for hepatoprotective activity in rats. The plant extract (250 mg/kg, p.o.) showed a remarkable hepatoprotective activity against acetaminophen-induced hepatotoxicity as judged from the serum markers for liver damage. Acetaminophen induced a significant rise in aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total bilirubin, gamma glutamate transpeptidase (GGTP) and decrease in total protein. Treatment of rats with ethanol extract (250 mg/kg) significantly (P<0.001) altered serum marker enzymes levels to near normal against acetaminophen treated rats. The activity of the extract was comparable to the standard drug, silymarin (50 mg/kg, p.o.). Histopathological changes of liver sample were compared with respective control. Results indicate that Clausena dentata possesses hepatoprotective effect on acetaminophen-induced hepatotoxicity in rats.

Abstract
IL-2 signaling appears to play a significant role in enabling the synthesis of T(h)2 cytokines in an in vitro system for studying primary T cell responses. When T cells from C57BL/6J or BALB/c strains of mice were activated in vitro and re-stimulated through their TCR complex 48 h later, CD4(+) T cells producing the T(h)2 cytokines IL-4 and IL-10 were found only when IL-2 was present. IL-2 also enhanced IFN-gamma synthesis in C57BL/6J cells but not in BALB/c cells. By up-regulating production of anti-inflammatory T(h)2 cytokines during a primary response, IL-2 may play a critical role in limiting T(h)1-mediated responses.

Abstract
Donor T cells that are activated by host alloantigens initiate graft versus host disease (GVHD) but their long-term fate is poorly understood. The behavior of alloreactive donor T cells was studied in sublethally irradiated SCID mice. Intravenous injection of 10(6) allogeneic lymphocytes caused a severe form of GVHD, characterized by host hematopoietic atrophy. Fifty-fold fewer donor cells did not induce disease and were not simply rejected by radioresistant host mechanisms. Instead, low numbers of allogeneic T cells expanded 20- to 50-fold and remained for >1 year without causing evidence of GVHD. Persistent non-cycling donor cells with an activated phenotype were mainly found in the spleen. Tolerance was inferred by the recovery of host hematopoiesis, despite the presence of donor allogeneic T cells, and the inability of long-term persisting donor T cells to mediate cellular cytotoxicity or proliferate in response to exogenous IL-2 or antigenic stimulation in vitro. The TCR density of long-term persisting donor T cells was down-regulated. These findings suggest that the development of GVHD depends on the magnitude of the initial anti-host response. Subsequently donor cells differentiate, over several months, into a senescent-like state. This behavior questions the rationale for current treatment approaches to GVHD and is of relevance to any clinical situation where chronic T cell activation takes place in the absence of thymic development.

Abstract
Despite defective granule exocytosis, T cells from mice whose perforin gene was ablated by homologous recombination (pko mice) caused a similar degree of graft-vs-host disease as normal T cells after injection into sublethally irradiated C.B-17 SCID mice. Moreover host spleens contained significantly greater numbers of T cells from pko mice than from wild-type mice following their i.v. injection. This increase could not be explained by persistence of host APCs that were not cleared by defective donor cytotoxic effector cells. The absence of functional perforin-dependent suppressor cells or an altered cytokine profile of donor T cells could also not account for the behavior of pko cells. Spontaneous and Fas-mediated apoptosis of in vivo activated donor T cells were independent of donor origin. However, pko T blasts exhibited less growth inhibition and cell death after reactivation in vitro. The results are compatible with a model of a defective activation-induced cell death (AICD) pathway, controlled by perforin, accounting for the increased expansion of alloreactive pko T cells.

Abstract
The dual specificity kinase SEK1 (MKK4) is a direct activator of stress-activated protein kinases (SAPK/JNK) in response to environmental stresses or mitogenic factors. We show in Sek1(-/-)Rag(-/-) chimeric mice that a Sek1 null mutation augments the susceptibility of peripheral T cells to TCR/CD3 religation-induced apoptosis. Sek1(-/-) T cells failed to induce expression of the death suppressor Bcl-XL in response to Ag receptor activation. The Sek1 mutation did not alter the induction of apoptosis in response to etoposide, cisplatinum, Adriamycin, and gamma-irradiation. Moreover, we show that CD3epsilon activation alone leads to SEK1 activation in Sek1(+/+) T cells. These results suggest that SEK1 transduces cellular survival signals during T cell stimulation.

Abstract
The granule exocytosis pathway of T cell cytotoxicity is absent in mice whose perforin gene has been ablated by targeted mutagenesis. The ability of activated naive T cells to undergo apoptosis in vitro following reaggregation of the TCR complex with anti-TCR mAbs via a Fas-independent pathway was found to be defective in the absence of perforin. Protection from death was most marked in CD8+ T cells. In wild-type cells, perforin was expressed at the same time that apoptosis occurred, and blockade of perforin expression by either incubation with perforin antisense oligonucleotides or with anti-IL-2 Abs resulted in increased viability of activated T cells. The role of perforin was not via perforin-dependent fratricidal killing. The results suggest a model in which perforin acts internally to cause a form of activation-induced T cell death distinct from that caused by members of the TNFR superfamily.

Abstract
Activated T cells from MRLlpr/lpr (lpr) mice have been shown to be resistant to TCR-induced apoptosis (activation-induced cell death) in vitro. We have found that this resistance is related to a defect in IL-2R alpha (CD25) expression and IL-2 signaling. Following primary activation, splenic T cells from 8-week old lpr mice failed to undergo apoptosis after the TCR was religated upon reculture with plate-bound anti-CD3 mAb. These cells had markedly reduced levels of IL-2 secretion and CD25 expression during primary activation in vitro; however, the cells still progressed through the cell cycle and were capable of cell division following TCR religation. Addition of exogenous IL-2 during the primary activation of 8-week-old lpr T cells overcame the defect in CD25 expression. Strikingly, these cells also became sensitive to apoptosis induction and died when the TCR was religated with anti-CD3 mAb. Viable cell recovery of both the lpr CD4+ and CD8+ subsets, as well as the CD4-CD8- subsets, was dramatically reduced under these conditions. Further investigation also revealed that the defect in activation-induced apoptosis in T cells from lpr mice was age-related. Activated T cells from young lpr mice (5 weeks old) underwent apoptosis in response to TCR ligation; these cells also expressed normal levels of CD25 following primary activation. However, as the mice aged from 5 to 8 weeks, susceptibility to TCR-mediated apoptosis in vitro was progressively lost together with the ability to express CD25. Our results suggest that before the onset of severe lymphoaccumulation, activated T cells from young lpr mice possess the capability to undergo TCR-induced apoptosis despite defective fas expression; IL-2 participates in sensitizing the cells to this death pathway. In older mice, this pathway breaks down and, together with the lack of fas-induced apoptosis, may account for the onset of severe lymphoaccumulation and autoimmunity.

Abstract
In the biology of a cell, the central role of p53 in controlling functions such as G1/S transition (check point) and DNA damage repair, and as a trigger of apoptosis, is well established. Somatic mutations or other changes in P53 have been reported in numerous tumor types, and in some of these, they are associated with poor prognosis. In this study, we examined 237 cytogenetically characterized B-cell non-Hodgkin's lymphomas (B-NHLs) for somatic changes in P53 by Southern blot analysis, by single-strand conformation polymorphism analysis (SSCP) of exon 5 through 9, and by direct sequencing of SSCP variants to determine the frequency and types of mutations and their clinical significance. In a portion of these (173 tumors), we also studied p53 expression by immunostaining. On Southern blots, no gross change was identified in P53 and no mutation was identified in exon 9. In exons 5 through 8, 27 different mutations were identified in 25 patients (23 single-base substitutions, 3 deletions, 1 duplication). Mutations in P53 were identified in 25 of 237 tumors (10.5%), which included 1 of 45 small lymphocytic lymphomas (SLLs), 2 of 38 follicular small cleaved-cell lymphomas (FSCCs), 2 of 35 follicular mixed small cleaved-cell and large-cell lymphomas (FMxs), 1 of 4 follicular large-cell lymphomas (FLCs), 1 of 14 diffuse small cleaved-cell lymphomas (DSCCs), 2 of 17 diffuse mixed small- and large-cell lymphomas (DMxs), and 16 of 84 diffuse large-cell lymphomas (DLCCs); the difference between the histologic groups was significant (P < .01). Among mantle-cell lymphoma (MC) patients, 3 of 10 had mutations. In 16 patients, the mutation was identified in specimens obtained at diagnosis. Mutation of transition type and transversion type occurred at a relative frequency of 2:1. Thirty percent occurred at CpG dinucleotide sequences and the codon for arginine was most frequently affected. Nineteen of 99 tumors with complex cytogenetic abnormalities, but none of 69 tumors with simple cytogenetic abnormalities, had mutations (P < .001). Similarly, 11 of 25 tumors with an abnormality of 17p and 8 of 143 tumors with apparently normal 17p had mutations (P < .0001). Positive correlations were found between a mutation and p53 expression (P < .001), between missense type mutations and p53 expression (P < .005), and between 17p abnormalities and p53 expression (P < .05). Twenty-two of 49 patients without mutation and 14 of 17 patients with mutations died (P < .05), but there was no significant difference in median survival. Similarly, 21 of 26 p53 positive patients died, whereas only 1 of 24 p53-negative patients died on-study (P < .001). Among p53-negative patients, mutation (P < .01) was positively associated with a fatal outcome. These findings indicate that in B-NHL, somatic changes in P53 were present in diagnostic specimens of all histologic types, but at a higher frequency in DLC and MC tumors. P53 mutation and/or expression has a negative influence on survival, and therefore can serve as prognostic indicators. Immunostaining for p53 is an effective way to screen for P53 changes in these tumors.
