Abstract
Abstract
Background
Heart transplant (HTx) patients can develop graft dysfunction (GD) without biopsy evidence of cell or antibody mediated rejection. Cardiac MRI (CMR) can detect inflammatory or infiltrative causes of cardiomyopathy however CMR findings in HTx recipients with GD have not been previously described.
Purpose
We sought to identify CMR characteristics of HTx patients with GD, and evaluate its additive value in its diagnosis and prognosis.
Methods
CMR has been performed routinely to evaluate GD at our institutions. There were 37 HTx recipients who presented with acute decline in left ventricular ejection fraction (LVEF) of <50% and >10% from baseline, with no biopsy evidence of rejection between 2007 and 2018. Coronary angiogram with IVUS was done to rule out allograft vasculopathy. Treatment of GD was per discretion of the treating clinician. Responders were defined as those with LVEF improvement >10% at 180 days or greater post-presentation. LV and RV indices, the presence and pattern of late gadolinium enhancement (LGE) were determined by CMR.
Results
There were 34% females and mean age at transplant was 49±13 years. Median time from HTx to GD was 1.2 years. Presenting symptoms were heart failure (n=25), cardiogenic shock (n=1) and 11 patients were asymptomatic. Mean LVEF at presentation was 37±12% and donor specific antibodies were detected in 38% patients. Most patients were treated with steroid bolus (n=29), and/or plasmapheresis (n=23). There were no major changes made in immunosuppression in 6 patients. Delayed enhancement MRI was performed with standard inversion-recovery (IR) gradient echo sequences, between 5 and 20 minutes after institutional-standard protocol administration of IV gadolinium contrast. Biventricular LGE was present in 18/37 (49%) patients with GD and was more prevalent in responders (57%, 13 of 23) than non-responders (35%, 5 of 14), although not statistically significant (p=0.21). There were two patterns of LGE noted: 1) Diffuse epicardial (10 patients out which 9 were responders) and 2) Patchy pattern with non-specific distribution (8 patients out of which 4 were responders). Myocardial edema by triple IR sequencing was seen in 6 patients, all having diffuse epicardial pattern of enhancement matching the delayed enhancement pattern. When comparing different treatment groups, among those treated for GD (n=31), 12 of 21 (57%) responders had LGE and 4 of 10 (40%) non-responders had LGE (p=0.37), a pattern similar to the broader population. Among those not treated for GD (n=6), 1 of 2 responders had LGE and 1 of 4 non-responders had LGE (p=0.5).
Conclusion
CMR identified inflammation as a potential cause of GD in approximately 50% of HTx patients. There are 2 distinct patterns of LGE observed in GD, diffuse epicardial (56%) and patchy (44%). Although the presence of LGE in itself is not associated with myocardial recovery, 90% of patients with a diffuse epicardial pattern have recovery of GD.

Abstract
Rapamycin, an mTOR inhibitor affects senescence through suppression of senescence-associated secretory phenotype (SASP). We studied the safety and feasibility of low-dose rapamycin and its effect on SASP and frailty in elderly undergoing cardiac rehabilitation (CR). 13 patients; 6 (0.5mg), 6 (1.0mg), and 1 patient received 2mg oral rapamycin (serum rapamycin <6ng/ml) daily for 12 weeks. Median age was 73.9±7.5 years and 12 were men. Serum interleukin-6 decreased (2.6 vs 4.4 pg/ml) and MMP-3 (26 vs 23.5 ng/ml) increased. Adipose tissue expression of mRNAs (arbitrary units) for MCP-1 (3585 vs 2020, p=0.06), PPAR-γ (1257 vs 1166), PAI-1 (823 vs 338, p=0.08) increased, whereas interleukin-8 (163 vs 312), TNF-α (75 vs 94) and p16 (129 vs 169) decreased. Cellular senescence-associated beta galactosidase activity (2.2% vs 3.6%, p=0.18) tended to decrease. We observed some correlation between some senescence markers and physical performance but no improvement in frailty with rapamycin was noted. (NCT01649960).

Abstract
BACKGROUND Caregiver burden in dementia is an important area of research. Providing care for a relative can be a potent source of chronic stress and can have deleterious consequences for both the physical and emotional health of caregivers. This study aims to evaluate the burden of care in caregivers of patients with Alzheimer-type dementia and compare it with elderly psychosis; and to also study the factors that influence burden of care in Alzheimer's dementia. METHODS Thirty-two caregiver-patient dyads of Alzheimer-type dementia were compared with thirty-two caregiver-patient dyads of psychosis. Cognitive assessment, abilities to perform activities of daily living and severity of dementia was assessed in the patients. Zarit Burden Interview was used to study the caregiver burden in both groups. RESULTS The mean burden score in dementia caregivers was high at 47.7, whereas the mean burden score for elderly psychosis caregivers was lesser at 33.6, and this difference in mean burden scores was found to be statistically significant. Spouses had the highest mean burden scores of 53.48. Caregiver burden in dementia was positively correlated with cognitive impairment and inability to carry out ADLs. Presence of psychological distress in caregivers was also an indicator for greater caregiver burden in dementia. CONCLUSION The study revealed that dementia carries a greater caregiver burden when compared with elderly patients with psychosis. Innovative interventions are needed to remove burden from caregiving, making it a meaningful practice integral to the Indian society.

Abstract
Weyl fermions have recently been observed in several time-reversal-invariant semimetals and photonics materials with broken inversion symmetry. These systems are expected to have exotic transport properties such as the chiral anomaly. However, most discovered Weyl materials possess a substantial number of Weyl nodes close to the Fermi level that give rise to complicated transport properties. Here we predict, for the first time, a new family of Weyl systems defined by broken time-reversal symmetry, namely, Co-based magnetic Heusler materials XCo_{2}Z (X=IVB or VB; Z=IVA or IIIA). To search for Weyl fermions in the centrosymmetric magnetic systems, we recall an easy and practical inversion invariant, which has been calculated to be -1, guaranteeing the existence of an odd number of pairs of Weyl fermions. These materials exhibit, when alloyed, only two Weyl nodes at the Fermi level-the minimum number possible in a condensed matter system. The Weyl nodes are protected by the rotational symmetry along the magnetic axis and separated by a large distance (of order 2π) in the Brillouin zone. The corresponding Fermi arcs have been calculated as well. This discovery provides a realistic and promising platform for manipulating and studying the magnetic Weyl physics in experiments.

Based on the ab initio calculations, we show that MoTe_{2}, in its low-temperature orthorhombic structure characterized by an x-ray diffraction study at 100 K, realizes 4 type-II Weyl points between the Nth and (N+1)th bands, where N is the total number of valence electrons per unit cell. Other WPs and nodal lines between different other bands also appear close to the Fermi level due to a complex topological band structure. We predict a series of strain-driven topological phase transitions in this compound, opening a wide range of possible experimental realizations of different topological semimetal phases. Crucially, with no strain, the number of observable surface Fermi arcs in this material is 2-the smallest number of arcs consistent with time-reversal symmetry.

Abstract
The aim of the present study is to investigate whether nicotine augmented the testicular toxicity and angiotensin converting enzyme inhibitor, enalapril, can ameliorate the effects in diabetic rat. Male Sprague Dawley rats were randomized into five groups: control, nicotine, diabetic, Diab + Nico, and Diab + Nico + Enal. Animals were made diabetic by single injection of streptozotocin (55 mg/kg/intraperitoneally). Nicotine dissolved in drinking water at a concentration of 100 µg/ml was given ad libitum and enalapril was given orally at a dose of 10 mg/kg/day for four consecutive weeks. After 4 weeks of treatment, animals were killed and biochemical parameters glucose, glycosylated hemoglobin, cotinine, and the testosterone levels were measured. Testicular toxicity was evaluated using sperm count, sperm comet assay, histology, and immunohistochemical staining of 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxo-dG) and the proinflammatory markers (nuclear factor kappa B (NF-κB), cyclooxygenase (COX-2), and tissue necrotic factor alpha (TNF-α)) evaluated by western blotting. Results showed that nicotine did not alter the blood glucose and glycosylated hemoglobin level, significantly decreased the sperm count and increased the sperm DNA damage. These changes were accompanied by significant increases in the 8-oxo-dG, NF-κB, COX-2, and TNF-α expression. Furthermore, the intervention of enalapril in nicotine-treated diabetic rat attenuated the testicular damage and restored sperm count, sperm DNA damage, as well as reduced the expression of NF-κB, COX-2, and TNF-α. These findings clearly suggest that nicotine not only augmented the testicular toxicity in the diabetic rat but also increases the risk of germ cell toxicity effects that were attenuated by enalapril treatment.

Abstract
Palm shell-based adsorbents prepared under five different thermochemical conditions and palm shell powder have been shown to be quite effective for removal of uranium from aqueous solutions. X-ray photoelectron spectroscopy (XPS), extended X-ray absorption fine structure (EXAFS), and Fourier transform infrared spectroscopy (FTIR) have been used to determine information about the speciation and binding of uranium on the adsorbents under study. Studies indicate that the uranium which is present as uranyl ion in aqueous solution is present in mixed valence states (U(IV), U(V), and U(VI)) when it is bound to the adsorbents. The mechanism of adsorption is likely to be adsorption-coupled reduction as well as complexation. Adsorption of uranium, cesium, and iron was found to be quantitative in binary as well as ternary mixtures.

Abstract
BACKGROUND Alzheimer's disease (AD), a progressive brain disorder, is the most common cause of dementia among the elderly. Donepezil hydrochloride is a potent, reversible, and highly selective inhibitor of acetylcholinesterase (AChE). It is chemically distinct from other cholinesterase (ChE) inhibitors which are effective in the treatment of AD. OBJECTIVES To evaluate the safety and efficacy of donepezil hydrochloride therapy over a 12 weeks period in patients with mild to moderate AD in Indian population. MATERIALS AND METHODS In this post-marketing study, patients with mild to moderate AD received oral donepezil hydrochloride 5 mg/day for 4 weeks followed by 10 mg/day for 8 weeks. Patients were assessed 4 times weekly for cognition on 'Mini Mental Status Examination (MMSE) scale', and function on 'Activities of Daily Living (ADL) index'. Clinicians and caregivers assessment of safety and efficacy was assessed on a 5-point rating scale. RESULTS One hundred and seventy two of one hundred and eighty two patients completed 12 weeks of study period. MMSE score significantly improved (P<0.0001) from 16.72 at baseline to 19.77 after 12 weeks, and there was significant improvement (P<0.05) in ADL index in 13 of 17 domains after 12 weeks. Caregivers and clinicians rated the therapy as very good to good in >80% and >90% patients, respectively. Adverse events were consistent with the known pharmacological and safety profile of donepezil. CONCLUSIONS Donepezil is well tolerated in Indian patients with mild to moderate AD with significant improvement in cognition and function.

Abstract
We report a case of a 30-year-old immunocompetent man with disseminated cryptococcosis who was initially treated with antitubercular therapy due to clinical and radiological diagnosis of vertebro-cerebral tuberculosis. The diagnosis of Cryptococcus infection was made due to incidental isolation of this fungus from blood culture with negative cerebrospinal fluid culture results. Though disseminated cryptococcosis with central nervous system, skeletal, and skin involvement is an uncommon manifestation of Cryptococcus neoformans infection, a high clinical suspicion and early initiation of therapy is needed to recognise and treat such patients efficiently.

Abstract
This randomized, comparative, multinational phase 3b/4 study of patients 1-8 years postcardiac transplantation (mean 3.9 years) evaluated the effect of conversion from a calcineurin inhibitor (CNI) to sirolimus on renal function in patients with renal insufficiency. In total, 116 patients on CNI therapy with GFR 40-90 mL/min/1.73 m(2) were randomized (1:1) to sirolimus (n = 57) or CNI (n = 59). Intent-to-treat analysis showed the 1-year adjusted mean change from baseline in creatinine clearance (Cockcroft-Gault) was significantly higher with sirolimus versus CNI treatment (+3.0 vs. -1.4 mL/min/1.73 m(2) , respectively; p = 0.004). By on-therapy analysis, values were +4.7 and -2.1, respectively (p < 0.001). Acute rejection (AR) rates were numerically higher in the sirolimus group; 1 AR with hemodynamic compromise occurred in each group. A significantly higher treatment discontinuation rate due to adverse events (AEs; 33.3% vs. 0%; p < 0.001) occurred in the sirolimus group. Most common treatment-emergent AEs significantly higher in the sirolimus group were diarrhea (28.1%), rash (28.1%) and infection (47.4%). Conversion to sirolimus from CNI therapy improved renal function in cardiac transplant recipients with renal impairment, but was associated with an attendant AR risk and higher discontinuation rate attributable to AEs.

Abstract
Increased production of reactive oxygen species under diabetic condition underlines the higher oxidatively damaged DNA in different tissues. However, it is practically difficult to assess the oxidatively damaged DNA in different internal organs. Therefore, the present study was aimed to evaluate the extent of oxidative stress-induced DNA damage in different organs with the progression of diabetes. Diabetic and control Sprague Dawley rats were sacrificed in time-dependent manner and the lung, liver, heart, aorta, kidney, pancreas and peripheral blood lymphocytes (PBL) were analyzed for both alkaline and modified comet assay with endonuclease-III (Endo III) and formamidopyrimidine-DNA glycosylase (FPG) (hereafter called modified comet assay) for the detection of oxidative DNA damage. The statistically significant increase in olive tail moment (OTM) was found in all the tested tissues. The extent of DNA damage was increased with the progression of diabetes as revealed by the parameter of OTM in alkaline and modified comet assay. Further, the positive correlations were observed between OTM of the lung, liver, heart, aorta, kidney and pancreas with PBL of diabetic rat in the alkaline and modified comet assay. Moreover, significant increase in the 8-oxodG positive nuclei in the lung, liver, heart, aorta, kidney and pancreas was observed in 4th and 8th week diabetic rat as compared to control. Results of the present study clearly indicated the suitability of alkaline and modified comet assay for the detection of multi-organ oxidative DNA damage in streptozotocin (STZ)-induced diabetic rat and showed that damaged DNA of PBL can be used as a suitable biomarker to assess the internal organs response to DNA damage in diabetes.

Abstract
Prostatic hyperplasia is a common problem of the aged men population. Recent experimental and clinical studies provide sufficient evidence that apart from androgens, insulin also plays an important role in the pathogenesis of prostatic hyperplasia. The present study was aimed to investigate the relative influence of testosterone and insulin on the cellular proliferation and prostatic growth. Effect of testosterone on the prostate of hypoinsulinemic, and glandular injection of insulin-receptor antagonist S961 on the prostate of castrated Sprague-Dawley rat (220±10 g) was examined. Significant decrease in the weight of the ventral prostate was observed in the streptozotocin-induced hypoinsulinemic rats (~6 fold), which is restored by the intervention of testosterone. Although, glandular injection of S961 did not led to any change in the frequency of proliferating cell nuclear antigen (PCNA) positive cells in normal rats, significant decrease was observed in the castrated rats. Castration led to increase in the frequency of the caspase-3 and the TUNEL positive cells in the ventral prostate. Further, long-term (6 weeks) administration of S961 induced significant decrease in the weight of the ventral prostate. Results of the present study provide that both testosterone and insulin promote prostatic cell proliferation and change in the level of either of the hormone results in the destabilization of cellular equilibrium, and modulation of the insulin-receptor signaling in the prostate may provide an alternative strategy for the treatment of prostatic enlargement. Further, studies are required to better understand the interplay between these hormones in the regulation of prostatic growth.
