Abstract
Mesenteric vascular thrombosis, typically of the superior mesenteric artery, is a frequent occurrence in patients with hypercoagulable conditions. Isolated involvement of the celiac artery is rare. Patients with celiac artery thrombosis can present with an acute abdomen or occasionally with acid peptic symptoms. A delay in diagnosis is associated with high rates of morbidity and mortality. We present a rare case of splenic infarction with celiac trunk thrombosis in a 54-year-old patient with underlying antiphospholipid (APLA) syndrome who presented with epigastric pain that was mistaken for symptoms of acid reflux.

Abstract
Leaves of jamun collected as agro by-produce during the cultivation of jamun is traditionally used as ayurvedic medicine to treat diabetes, gall bladder stones and other ailments. Most of the beneficial effects of jamun leaves are associated with phytochemicals found in jamun leaves such as gallic acid, tannins, mallic acid, flavonoids, essential oils, jambolin, ellagic acid, jambosine, antimellin and betulinic acid. Jamun possess curative activities like anticancer, antidiabetic, antifertility, anti-inflammatory, antidiarrheal, antimicrobial, antinociceptive, antioxidant, antiradiation, chemotherapeutic, and gastroprotective. The main goal of this review article is to provide information on the nutritional content, phytochemical composition and health promoting properties of jamun leaves. The review of literature based on the phytochemical composition and health promoting benefits of the jamun leaves, suggests that leaves can be used as potential constituent in the formulation of pharmacological drugs. From the review literature it is found that clinical, in-vivo, in-vitro studies are still required to check the health promoting effects of jamun leaves extracts on humans.

Abstract
Pathogen-associated molecular patterns (PAMPs) like bacterial cell wall components and viral nucleic acids are known ligands of innate inflammatory receptors that trigger multiple inflammatory pathways that may result in acute inflammation and oxidative stress-driven tissue and organ toxicity. When dysregulated, this inflammation may lead to acute toxicity and multiorgan failure. Inflammatory events are often driven by high energy demands and macromolecular biosynthesis. Therefore, we proposed that targeting the metabolism of lipopolysaccharide (LPS)-driven inflammatory events, using an energy restriction approach, can be an effective strategy to prevent the acute or chronic detrimental effects of accidental or seasonal bacterial and other pathogenic exposures. In the present study, we investigated the potential of energy restriction mimetic agent (ERMA) 2-deoxy-D-glucose (2-DG) in targeting the metabolism of inflammatory events during LPS-elicited acute inflammatory response. Mice fed with 2-DG as a dietary component in drinking water showed reduced LPS-driven inflammatory processes. Dietary 2-DG reduced LPS-induced lung endothelial damage and oxidative stress by strengthening the antioxidant defense system and limiting the activation and expression of inflammatory proteins, viz., P-Stat-3, NfκΒ, and MAP kinases. This was accompanied by decreased TNF, IL-1β, and IL-6 levels in peripheral blood and bronchoalveolar lavage fluid (BALF). 2-DG also reduced the infiltration of PMNCs (polymorphonuclear cells) in inflamed tissues. Altered glycolysis and improved mitochondrial activity in 2-DG-treated RAW 264.7 macrophage cells suggested possible impairment of macrophage metabolism and, therefore, activation in macrophages. Taken together, the present study suggests that inclusion of glycolytic inhibitor 2-DG as a part of the diet can be helpful in preventing the severity and poor prognosis associated with inflammatory events during bacterial and other pathogenic exposures.

Abstract
Human awareness of the need for health and wellness practices that enhance disease resilience has increased as a result of recent health risks. Plant-derived polysaccharides with biological activity are good candidates to fight diseases because of their low toxicity. Tinospora cordifolia (Willd.) Hook.f. & Thomson polysaccharides extract from different plant parts have been reported to possess significant biological activity such as anti-oxidant, anti-cancer, immunomodulatory, anti-diabetic, radioprotective and hepatoprotective. Several extraction and purification techniques have been used to isolate and characterize T. cordifolia polysaccharides. Along with hot-water extraction (HWE), other novel techniques like microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), pulsed electric field (PEF), supercritical-fluid extraction (SFE), and enzyme-assisted extraction (EAE) are used to extract T cordifolia polysaccharides. SFE is a revolutionary technology that gives the best yield and purity of low-molecular-weight polysaccharides. According to the findings, polysaccharides extracted and purified from T. cordifolia have a significant impact on their structure and biological activity. As a result, the methods of extraction, structural characterization, and biological activity of T. cordifolia polysaccharides are covered in this review. Research on T. cordifolia polysaccharides and their potential applications will benefit greatly from the findings presented in this review.

Abstract
Herein, we disclose a metal-free novel approach for the synthesis of N-(α-substituted)alkyl sulfoximines/sulfonimidamides via one-pot multicomponent Petasis reactions of aryl boronic acids, ortho-hydroxyarylaldehydes and sulfoximines/sulfonimidamides in moderate to very good yields. The presence of two chiral centres provides a mixture of diastereomers almost in a 1 : 1 ratio, which are separated successfully in most of the cases. The -OH functionality of Petasis products is further utilized to derive heterocycles via O-allylation, followed by intramolecular Heck cyclization, proving the synthetic utility of the products.

Abstract
Aim
The COVID19 pandemic has accelerated the need for staff to work remotely. Our aim was to demonstrate how a next-generation digital platform could be used to create a virtual MDT ecosystem in order to manipulate holographic 2D and 3D images in real-time.
Method
This study involved setting up a mock virtual MDT using de-identified DICOM files from a patient who had been treated for colorectal cancer and then subsequently found to have a liver metastasis. The image file was segmented and converted into a 2D and 3D format for visualisation within Microsoft HoloLens 2 ® (smart glasses) using Holocare Solutions ® (Mixed Reality software).
Results
A seamless cross-border pipeline was developed that involved "clinician" training, DICOM segmentation and virtual connection. We successfully performed a virtual MDT with participants able to visualise and manipulate a virtual 3D organ in real-time. The digital network remotely connected sites in England and Norway. The streaming quality was stable and HIPAA compliant. Each participant could observe others as "avatars" interacting with images within the virtual ecosystem allowing image characteristics to be highlighted.
Conclusions
We successfully conducted a virtual MDT using novel hardware and software. Our intention is to conduct a large-scale study to assess the platform's effectiveness in “Real World" MDTs.

Abstract
AIM To investigate machine learning based models combining clinical, radiomic, and molecular information to distinguish between early true progression (tPD) and pseudoprogression (psPD) in patients with glioblastoma. MATERIALS AND METHODS A retrospective analysis was undertaken of 76 patients (46 tPD, 30 psPD) with early enhancing disease following chemoradiotherapy for glioblastoma. Outcome was determined on follow-up until 6 months post-chemoradiotherapy. Models comprised clinical characteristics, O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status, and 307 quantitative imaging features extracted from enhancing disease and perilesional oedema masks on early post-chemoradiotherapy contrast-enhanced T1-weighted imaging, T2-weighted imaging (T2WI), and apparent diffusion coefficient (ADC) maps. Feature selection was performed within bootstrapped cross-validated recursive feature elimination with a random forest algorithm. Naive Bayes five-fold cross-validation was used to validate the final model. RESULTS Top selected features included age, MGMT promoter methylation status, two shape-based features from the enhancing disease mask, three radiomic features from the enhancing disease mask on ADC, and one radiomic feature from the perilesional oedema mask on T2WI. The final model had an area under the receiver operating characteristics curve (AUC) of 0.80, sensitivity 78.2%, specificity 66.7%, and accuracy of 73.7%. CONCLUSION Incorporating a machine learning-based approach using quantitative radiomic features from standard-of-care magnetic resonance imaging (MRI), in combination with clinical characteristics and MGMT promoter methylation status has a complementary effect and improves model performance for early prediction of glioblastoma treatment response.

Abstract
Oncocytoma is a rare epithelial tumour composed of oncocytes which are epithelial cells with excessive amount of mitochondria. The tumour is most often benign, and diagnosis can be made on the basis of histopathological examination. Here, the authors present a 64-year-old female patient, with complaints of abdominal discomfort and flank pain, along with history of loss of weight and appetite for one month. Radiology showed a left renal mass of measuring 9×7×4.5 cm involving the upper and middle pole suggestive of malignancy. Following which radical nephrectomy was done. Examination of gross specimen showed a fairly circumscribed brownish lesion in the upper and middle pole of left kidney measuring 8.8×7×4.5 cm with a central scar. There was no evidence of hilar and perirenal fat invasion. Histology showed sheets of large polygonal eosinophilic cells with centrally placed nucleus. The differentials were eosinophilic variant of clear cell renal cell carcinoma, chromophobe renal cell carcinoma and oncocytoma. A panel of Immunohistochemical (IHC) markers was performed for further categorisation and the lesional cells were positive for CD 117 and negative for CD 7 and CD 10. This ruled out the differentials and confirmed oncocytoma, thus ruling out the necessity for chemotherapy.

Abstract
Pathogen-associated molecular patterns (PAMPs) associated with viral and bacterial infections trigger multiple inflammatory pathways which may result in oxidative stress driven toxicity, tissue fibrosis organ dysfunction and ageing. Inflammatory events need high energy demands and predominantly depends on the glycolysis. Thus, energy metabolism of the inflammatory events can be targeted to reducing the magnitude of the PAMPs driven inflammation and preventing tissue toxicity. Here we propose that 2-DG, a glycolytic inhibitor, and a potential Energy Restriction Mimetic agent (ERMA) can modulate inflammatory events and can prevent the development of acute as well as chronic pathology. For this study we induced LPS (bacterial PAMP) induced endotoxemia in mice which models infection associated inflammatory acute inflammatory events, tissue damage and organ dysfunction. 2-DG fed mice (0.4% w/v in drinking water) showed reduced LPS driven oxidative stress and capillary damage in lungs. Administration of 2-DG also reduced LPS induced spike in inflammatory cytokines (TNF, IL6 and IL1β) in the BALF and serum. Lungs of 2-DG fed mice showed lesser infiltration of inflammatory cells and reduced inflammatory signaling activation. 2-DG also downregulated the ex-vivo and in-vivo migration of the PMNCs. Furthermore, 2-DG also reduced the activation of the macrophage cells (RAW264.7) which was seen with reduction and the glycolysis and increased mitochondrial functions. Our data suggest that 2-DG administration as ERMA in drinking water can prevent pathogenic exposure driven inflammatory events which may prevent acute as well as chronic inflammatory disorders.

Obesity is a major risk factor for type 2 diabetes, NAFLD, chronic diseases and cancer. Insulin resistance, oxidative stress, high ectopic lipid levels and meta-inflammation are the mechanisms proposed to play a leading role in the morbidity associated with obesity. Energy restriction mimetics (ERMAs) has also been shown earlier to reduce the scale and the severity of these disorders by mimicking the physiological effects of the Energy Restriction. In present study we propose that the use of 2-DG as ERMA can be effective in regulating the High Fat Diet (HFD) induced obesity. Effect of 2-DG (0.4% w/v in drinking water) on the HFD and Insulin Resistance (IR). HFD induced change in body weight, adipose tissue mass, and ectopic lipid levels was assessed as the measure of obesity.IR and glucose levels were also estimated to evaluate the effect of 2-DG on the insulin sensitivity in HFD mice. 2-DG significantly altered HFD induced increase in the mice body weight, epididymal White Adipose Tissue (WAT) and liver weight. 2-DG fed mice also showed reduced lipid levels in serum and liver. Furthermore, 2-DG also reduced the oxidative damage in the liver with concomitant increase in enzymatic (SOD and Catalase) and non-enzymatic (reduced Glutathione) antioxidant levels. 2-DG fed mice also showed reduced levels of Leptin, IL-6 and TGF-β which are early drivers of the etiology of the metabolic diseases. Our results suggest that 2-DG as ERMA can prevent obesity and etiology of associated disorders. However, more relevant models are needed to further strengthen these observation

Abstract
Introduction: Horseshoe Kidneys (HSK) are the most common congenital fusion of the kidneys. After the reports of Wickham and Kellet in 1981 and Clayman in 1983, percutaneous extraction of stones in HSKs has been widely adopted. In this era of advancement of Retrograde Intra Renal Surgery (RIRS), Percutaneous Nephrolithotomy (PCNL) still holds strong position for HSK stone management, due to HSK vascular and pelvicalyceal anatomy. Aim: To evaluate PCNL in managing large HSK stone disease in the form of stone free rate and to assess procedure related complication between October 2016 to March 2020. Materials and Methods: A retrosepective cross-sectional study was conducted between October 2016 to March 2020, in total of 18 patients (21 renal units) underwent PCNL for stone disease in HSK. Stone size >1.5 cm, failed Extra-Corporeal Shockwave Lithotripsy (ESWL) and recurrent stones were included in the study. Results: Mean age of the patients was 40.67±7.87 years, 12 were male and 6 were female. Three patients had stones in both renal units. The mean stone size was 22.19±7.43 (12.00-46.00) mm. Twelve units had stone in the pelvis (57.1%), 6 unit in upper calyx (28.6%). One unit (4.8%) had stone in isthmus and 3 units (14.3%) had staghorn calculi. Access site was upper calyx in majority 76.2% of the cases, 23.8% required additional puncture most commonly through middle calyx. Total 8 patients had postoperative complications, fever being the most common (19%). Complete clearance was obtained in 85.7%, while 14.3% had residual calculi for which ancillary procedures were performed. Conclusion: PCNL can be recommended as the first line of management in the treatment of HSKs with large stone burden, considering its higher clearance rate and minimal complications.

Abstract
Begomoviruses are the largest group of plant viruses transmitted exclusively by the whitefly, Bemisia tabaci (Gennadius), in a persistent, circulative, and nonpropagative manner. Begomoviruses in association with B. tabaci cause enormous loss to world agricultural crops. Transmission, retention, and circulation of begomovirus in B. tabaci are facilitated by its interaction with several proteins of the insect and its endosymbionts. However, very few such proteins have been identified from B. tabaci that are involved in this specific interaction. Here, we have performed yeast two-hybrid assay between B. tabaci complementary DNA expression library and the coat protein (CP) of tomato leaf curl New Delhi virus (ToLCNDV) and cotton leaf curl Rajasthan virus (CLCuV). Collagen was the common protein found to be interacting with both of the viruses. The collagen protein was found to be localized in gut layers of B. tabaci. Additionally, pull-down and dot-blot assays confirmed the association of endogenous collagen with ToLCNDV CP. Immunolocalization analysis also showed colocalization of ToLCNDV particles and collagen within insect gut. Finally, B. tabaci fed on anticollagen antibody and exhibited ∼46% reduction in ToLCNDV transmission, suggesting a supportive role for collagen in virus transmission.

Abstract
This is a cross-sectional analysis of spin in randomized controlled trial (RCT) abstracts published in top-ranked obesity and general medicine journals. The top seven obesity and four general medicine journals were searched from 1 January 2016 to 31 December 2017. To be included in this study, a trial must be an RCT with non-significant primary endpoint (P > 0.05), exclusively randomize subjects with overweight or obesity or have a primary endpoint of weight loss. These studies were analysed by two reviewers for spin in the abstract. The primary endpoint of our investigation was the frequency and type of spin. The secondary endpoint was to assess whether funding source was associated with the presence of spin. Our PubMed search yielded 1143 articles. Primary screening excluded 992 articles, and full-text evaluation excluded an additional 106. Overall, 45 articles were included. Spin was identified in 21 of the 45 (46.7%) abstracts analysed. Evidence of spin was found in 17 (37.8%) abstract result sections and 11 (24.4%) abstract conclusion sections. Of the 39 RCTs reporting a clinical trial registry, 6 (15.4%) had evidence of selective reporting bias. Our study found that obesity medicine RCTs from top-ranked journals with non-significant primary endpoints published in 2016 and 2017 frequently have spin in their abstracts. Abstracts with evidence of spin may influence a reader's perception of new drugs or procedures. These results warrant a careful review of future RCTs, but may not be generalizable to RCTs published in lower-ranked journals.

Abstract
INTRODUCTION Paediatric Auditory Brainstem Implantation (ABI) is indicated for children with congenital cochlear aplasia, absent/hypoplastic vestibulocochlear nerve, for whom cochlear implantation is not possible. Knowledge of the anatomical landmarks and variants in anatomy of the brainstem is vital for ABI surgery. METHOD Study was done at Auditory implant centre in Madras ENT research foundation, which includes 24 children who had undergone ABI surgery and are being followed up for 1 year, post operatively. Aims were to study the anatomical variants and the outcomes of ABI implantation. To determine if different anatomical variants effect placement of ABI electrode. To assess the patient outcomes by Categories of auditory Performance (CAP) scores and Speech Intelligibility Ratings (SIR) scores. RESULTS All the candidates showed gradual improvement in audiological and verbal outcomes after the ABI. The mean CAP and SIR scores after 6 months of AVHT were 2.07 and 1.37 respectively. After 1 year of auditory verbal rehabilitation therapy CAP was 3.42 and SIR was 2.33. Flocculus of the cerebellum can be of different grades. Though, there was difficulty in insertion of the electrode in subjects with anatomical variants, the outcomes were comparable with other subjects. CONCLUSION ABI surgery involves frequent anatomical variations surrounding the lateral recess which makes the positioning of the auditory prosthesis difficult. Variants during the surgery can make the placement of ABI electrodes difficult, but promising results were seen all the implantees.

Abstract
Studies were carried out on the toughening of a bifunctional epoxy (diglycidyl ether of bisphenol-A) matrix system with an ABS/PC thermoplastic blend. The thermoplastic blend was incorporated into the epoxy matrix by particle dispersion and melt-mix methods. The unmodified and modified epoxy resin systems were cured with a stoichiometric quantity of diamino diphenyl methane (DDM). The cured castings were characterized by measurement of glass transition temperature (Tg) by DsC, evaluation of plane strain fracture toughness (Klc) by three-point bending tests and SEM analysis of non-etched and base/acid etched fracture surfaces. In genera] ABS/PC-modified (15% w/w) epoxy-resin-cured systems showed enhanced fracture toughness without lowering the glass transition temperature. The melt-mix method yielded higher fracture toughness than the particle dispersion method; this conclusion was also supported by scanning electron micrographs.

Abstract
Abstract
Inflammation is a critical component and contributor of carcinogenesis. Toll like receptors (TLRs) are key regulators of innate immunity and inflammatory signaling. Besides various microbe-associated molecular patterns, TLRs can also bind to endogenously generated damage associated molecular patterns (DAMPS) ligands such as heat shock proteins, surfactant protein A18 and homobility group box-1(HMGB1). While HMGB1, a TLR-4 ligand is over-expressed in several human neoplasms, preclinical studies in mouse tumor models have strengthened the role of TLR-4-HMGB1 axis in promoting carcinogenesis. TLR-4 dependent inflammation and stimulation is accompanied with a switch from respiratory to glycolysis dominated metabolism, which is critical for the differentiation and maturation of myeloid cells thus affecting the outcome of an inflammatory disease. In the present studies we investigated the potential of the glycolytic inhibitor 2-deoxy-D-glucose (2-DG) as an energy restriction mimetic agent for countering the acute and chronic inflammation which can be employed as a cancer preventive strategy. Oral administration of 2-DG in drinking water (0.4% w/v) for 7 days reduced the diethyl nitrosamine (DEN) induced acute inflammation reflected by reduced the serum levels of TNF(∼4 fold) and IL-6(∼7 fold). when administered chronically, 2-DG reduced the incidence (∼50%) and the number of papillomas (∼84%) in DMBA-TPA skin carcinogenesis model, which correlated with the reduced levels of TNF. In an acute inflammation model established using LPS (a TLR-4 ligand), we observed that 2-DG reduced the systemic and macrophage specific inflammatory response in LPS injected mice. 2-DG (1mM) significantly reduced the levels of co-stimulatory surface markers (CD80 and CD86) and associated ROS and NOS effecter functions in mouse macrophagic cell line (RAW 264.7). These studies suggest that dietary administration of 2-DG can be used as a strategy for preventing acute inflammation and associated carcinogenesis.

Abstract
The innate immune system is an integral component of the inflammatory response to pathophysiological stimuli. Toll-like receptors (TLRs) and inflammasomes are the major sensors and pattern recognition receptors (PRRs) of the innate immune system that activate stimulus (signal)-specific pro-inflammatory responses. Chronic activation of PRRs has been found to be associated with the aggressiveness of various cancers and poor prognosis. Involvement of PRRs was earlier considered to be limited to infection- and injury-driven carcinogenesis, where they are activated by pathogenic ligands. With the recognition of damage-associated molecular patterns (DAMPs) as ligands of PRRs, the role of PRRs in carcinogenesis has also been implicated in other non-pathogen-driven neoplasms. Dying (apoptotic or necrotic) cells shed a plethora of DAMPs causing persistent activation of PRRs, leading to chronic inflammation and carcinogenesis. Such chronic activation of TLRs promotes tumor cell proliferation and enhances tumor cell invasion and metastasis by regulating pro-inflammatory cytokines, metalloproteinases, and integrins. Due to the decisive role of PRRs in carcinogenesis, targeting PRRs appears to be an effective cancer-preventive strategy. This review provides a brief account on the association of PRRs with various cancers and their role in carcinogenesis.

Abstract
The infection with high-risk human papillomavirus (HR-HPV) is the most important risk factor for development of cervical cancer. The intra-type variations of HPV have different biological and pathological consequences with respect to disease progression. In the present study, six major Indian variants were experimentally identified in E6 gene of HPV-16 and showed their impact on immunogenicity by in silico methods. Four different phylogenetic lineages were observed in sequences including European (E) prototype, European variant, Asian and American Asian variant classes and complete absence of African phylogenetic lineages. On the prediction of B- and T-cell epitopes, 18 and 23 potent epitopes for MHC-II alleles, 10 potent MHC-I and 15 B-cell epitopes in each reference and variant sequence were identified. Interestingly, the presence of variation H78Y and L83V result in creation of four new epitopes for the HLA-DQA1*0101/DQB1*0501. Out of 15 B-cell predicted epitopes, three most potent epitopes were identified in both reference and variant sequence. Notably the amino acid stretch from amino acid 16-60 and 76-94 are very important for the immunological properties of E6 protein because these regions contain majority of the predicted epitopes. In future, this could control the cervical cancer by targeting these amino acid stretches for the development of HPV-16 vaccine.

Abstract
The present investigation has been carried out on Tagetes erecta to search out the effect of sugar mill effluent on growth and yield. In-vivo conditions were set up for the experiment purpose. Pots were filled with soil and treated with different concentrations of sugar mill effluent i.e., 10, 25, 50, 75 and 100% on morphological parameters of test crop. Results of pot culture experiment showed that at 10 % concentrations of sugar mill effluent proved to better to the crops growth and thereafter the growth may reduce over control. In order to mitigate the effluent toxicity certain Biofertilizers inoculants were mixed to the soil along with the same effluent treatments. The study suggests that the Biofertilizers inoculants along with effluent irrigation proved to be better for plants growth.

Abstract
Partially degraded high-density polyethylene (HDPE) was collected from plastic waste dump yard for biodegradation using fungi. Of various fungi screened, strain MF12 was found efficient in degrading HDPE by weight loss and Fourier transform infrared (FT-IR) spectrophotometric analysis. Strain MF12 was selected as efficient HDPE degraders for further studies, and their growth medium composition was optimized. Among those different media used, basal minimal medium (BMM) was suitable for the HDPE degradation by strain MF12. Strain MF12 was subjected to 28S rRNA sequence analysis and identified as Aspergillus terreus MF12. HDPE degradation was carried out using combinatorial physical and chemical treatments in conjunction to biological treatment. The high level of HDPE degradation was observed in ultraviolet (UV) and KMnO4/HCl with A. terreus MF12 treatment, i.e., FT10. The abiotic physical and chemical factors enhance the biodegradation of HDPE using A. terreus MF12.

Abstract
BACKGROUND Excessive postoperative hemorrhage in cardiac surgery is a serious complication associated with adverse postoperative events. Also, its associated risk of re-exploration, places a high demand on hospital resources in terms of transfusion needs, ventilatory support requirements, intensive care support, and manpower requirements. OBJECTIVE To determine predictors of 24-hour drain volume (pleural and mediastinal) after coronary artery bypass graft (CABG), in order to focus on preventive measures for patients with identified risk factors. PATIENTS AND METHODS Fifty-four consecutive adult patients who had CABG at the Madras Medical Mission, Chennai, India in July 2008 were retrospectively studied. In order to determine risk factors for excessive post-operative bleeding, 11 pre-operative, and 13 operative and 2 post-operative variables were analyzed using univariate analysis and multiple linear regression. RESULTS Cardiopulmonary bypass was used for all the patients and anti-fibrinolytic in 13 (22.8%). No mortality was recorded. Mean 24-hour post-operative drain volume was 458 ± 270 ml (range 90-1230). Re-exploration for bleeding was required in 2 (3.5%) patients. Predictors of 24-hour drain volume were heparin therapy before commencement of CPB (p=0.024), intra-operative transfusion of fresh frozen plasma (p=0.010), and pre-operative serum ALT value (p=0.047). The strongest predictor was intra-operative transfusion of platelets (p=0.005). CONCLUSION To guard against excessive post-operative haemorrhage after CABG, pre-operative stabilisation and correction of coagulation should be achieved. Also the administration of heparin intra-operatively should be individualized and not only based on dose per body weight.

Abstract
The efficacy of methotrexate (MTX), a widely used chemotherapeutic drug, is limited by its gastrointestinal toxicity and the mechanism of which is not clear. The present study investigates the possible role of mitochondrial damage in MTX-induced enteritis. Small intestinal injury was induced in Wistar rats by the administration of 7 mg kg(-1) body wt. MTX intraperitoneally for 3 consecutive days. MTX administration resulted in severe small intestinal injury and extensive damage to enterocyte mitochondria. Respiratory control ratio, the single most useful and reliable test of mitochondrial function, and 3-(4,5-dimethylthiazol-2-yll)-2,5-diphenyltetrazolium bromide reduction, a measure of cell viability were significantly reduced in all the fractions of MTX-treated rat enterocytes. A massive decrease (nearly 70%) in the activities of complexes II and IV was also observed. The results of the present study suggest that MTX-induced damage to enterocyte mitochondria may play a critical role in enteritis. MTX-induced alteration in mitochondrial structure may cause its dysfunction and decreases the activities of the electron chain complexes. MTX-induced mitochondrial damage can result in reduced adenosine triphosphate synthesis, thereby interfering with nutrient absorption and enterocyte renewal. This derangement may contribute to malabsorption of nutrients, diarrhea, and weight loss seen in patients on MTX chemotherapy.
