Abstract
Polatuzumab vedotin is a novel immunotherapy antibody-drug conjugate targeting CD79b. It has been used in relapsed/refractory (R/R) large B-cell lymphomas since its FDA approval in 2019. Presently, this drug is unaffordable or unavailable for patients in Lower-Middle Income Countries (LMIC) like India. This is a retrospective study of adult (> 18 years) patients with R/R large B-cell lymphoma failing two prior lines of therapy, who received Polatuzumab based salvage therapy on a compassionate or named-patient access program. Between May 2019 and April 2022, 10 patients received Polatuzumab vedotin, and 9 were evaluable. The most common regimen used was Polatuzumab-Bendamustine-Rituximab. Out of 43 infusions administered, the adverse event profile was manageable [One grade-2 infusion reaction, 4 patients developed grade 3-4 hematological toxicity and none had grade 3-4 non-hematological toxicities]. Ten infusions were administered in the day care service. After a median of 4.5 cycles (range 1-8), 4 patients achieved CR, 2 had partial response (PR), and 3 had progressive disease (PD). With a median follow up of 491 days (range 8-1048 days), four patients are alive (three in CR and one in PR), three patients have died and three patients were lost to follow up. Early real-world experience from a LMIC setting demonstrates feasibility and a favourable safety profile of Polatuzumab vedotin based approach, along with encouraging response rates in a subset of patients.

Abstract
BACKGROUND The excess amount of glutamate in neurons is associated with the excitotoxicity and neurodegenerative diseases. Glutamate induces neurotoxicity primarily by immense influx of Ca2+ arising from overstimulation of the NMDA subtype of glutamate receptors. The neuronal death induced by the overstimulation of glutamate receptors depends critically on a sustained increase in mitochondrial Ca2+ influx and impairment in mitochondrial functions. The mitochondrial impairment is an important contributor to the glutamate-induced neuronal toxicity and thus provides an important target for the intervention. The present study investigates the effects of high glutamate concentrations on mitochondrial functions. RESULTS Here, we have shown that the higher concentration of glutamate treatment caused a significant elevation in the N-methyl-D-aspartate (NMDA) receptors expression and elevated the intra-mitochondrial calcium accumulation in SHSY5Y neuronal cells. As a result of an accumulation of intra-mitochondrial calcium, there is a concentration-dependent elevation in ROS in the mitochondria. Tyrosine nitration of several mitochondrial proteins was increased while the mitochondrial membrane potential was dissipated. Furthermore, glutamate treatments also resulted in mitochondrial membrane permeability transition. CONCLUSIONS These findings suggest that treatment of high glutamate concentration causes impairment of mitochondrial functions by an increase in intra-mitochondrial calcium, ROS production, dissipation of mitochondrial membrane potential and mitochondrial permeability transition pore opening in human neuroblastoma SHSY5Y cells.

Abstract
Due to recent progress in the development of genetic tools, nematodes have become excellent models to address the mechanistic basis of evolution of development. The gonad is one of the most variable structures in nematodes, reflecting the diverse modes of reproduction and lifestyle in this phylum. During larval development, the gonad primordium has a key role in organizing the neighboring tissues. Therefore, changes in the development of the gonad do not only influence the evolution of its morphology but also the overall body plan of the nematode. Here, we review recent progress on the evolution of development of the germline and somatic gonad in nematodes.

Abstract
Thirty eight patients with essential hypertension and 20 healthy volunteers were subjected to treadmill exercise test. The hypertensives were then controlled with atenolol or captopril by randomly forming two groups of 19 patients each, and treadmill evaluation was repeated. The resting rate-pressure product (RPP) and myocardial oxygen consumption (MVO2), as well as peak RPP and MVO2 and recovery time, were increased and exercise duration decreased significantly in uncontrolled hypertensives (p less than 0.001). Control of hypertension resulted in significant improvement of exercise performance in both the groups. Atenolol, when compared to captopril, resulted in better exercise conditioning with considerable lowering of resting and peak RPP and MVO2 (p less than 0.001), though the difference in exercise duration, maximum work load and recovery time were not significant (p greater than 0.05). Thus, where myocardial oxygen consumption is an important consideration while treating hypertension, atenolol offers a better choice.
