Investigating metal (M = Mn, Fe, and Ni)-doped Co(OH) 2 nanofibers for electrocatalytic oxygen evolution and electrochemical biosensing performance
To achieve efficient and cost-effective electrochemical water splitting, highly active and affordable nanostructured catalysts are the key requirement. The current study presents the investigations of the efficacy of metal (Mn, Fe and Ni)-doped Co(OH)2 nanofibers towards oxygen evolution via water splitting. Notably, Ni-doped Co(OH)2 demonstrates superior OER performance in KOH electrolyte, surpassing standard IrO2 with a modest potential of 1.62 V at 10 mA cm−2. The remarkable activity is attributed to the nanofiber structure, facilitating faster conduction and offering readily available active sites. Ni-doped Co(OH)2 nanofibers displayed enduring stability even after 1000 cycles. This work underscores the importance of transition-metal based catalysts as effective electrocatalysts, providing the groundwork for the development of cutting-edge catalysts. Additionally, the electrochemical sensing capability towards ascorbic acid is evaluated, with Ni-doped Co(OH)2 showing the most promising response, characterized by the lowest LOD and LOQ values. These findings highlight the potential of Ni-doped Co(OH)2 nanofibers for upcoming diagnostic detection devices

Climate Smart Crops for Food Security
After ensuring the food security for over 50 years, the green revolution is eventually reaching its biological limits which are very much reflected by the ongoing stagnancy in yield increased over the past few decades. Meeting the increasing food demands due to increasing population is the greatest challenge for today’s plant scientists. Changing climatic conditions are posing additional threats to crop growth, productivity and yield. After successfully deploying gene editing to modify simple traits, scientists are now embarked on more ambitious adventures in genomics to combat challenges of food security in the wake of increasing population and climate change adversaries. The chapter outlines use of new technologies in tailoring crops beyond simple traits aiming to harvest the desired diversity lost during domestication and manipulating complex traits, which evolved over evolutionary timescale with special emphasis on the development of climate smart crops
shRNA-mediated gene silencing of HDAC11 empowers CAR-T cells against prostate cancer
Epigenetic mechanisms are involved in several cellular functions, and their role in the immune system is of prime importance. Histone deacetylases (HDACs) are an important set of enzymes that regulate and catalyze the deacetylation process. HDACs have been proven beneficial targets for improving the efficacy of immunotherapies. HDAC11 is an enzyme involved in the negative regulation of T cell functions. Here, we investigated the potential of HDAC11 downregulation using RNA interference in CAR-T cells to improve immunotherapeutic outcomes against prostate cancer. We designed and tested four distinct short hairpin RNA (shRNA) sequences targeting HDAC11 to identify the most effective one for subsequent analyses. HDAC11-deficient CAR-T cells (shD-NKG2D-CAR-T) displayed better cytotoxicity than wild-type CAR-T cells against prostate cancer cell lines. This effect was attributed to enhanced activation, degranulation, and cytokine release ability of shD-NKG2D-CAR-T when co-cultured with prostate cancer cell lines. Our findings reveal that HDAC11 interference significantly enhances CAR-T cell proliferation, diminishes exhaustion markers PD-1 and TIM3, and promotes the formation of T central memory TCM populations. Further exploration into the underlying molecular mechanisms reveals increased expression of transcription factor Eomes, providing insight into the regulation of CAR-T cell differentiation. Finally, the shD-NKG2D-CAR-T cells provided efficient tumor control leading to improved survival of tumor-bearing mice in vivo as compared to their wild-type counterparts. The current study highlights the potential of HDAC11 downregulation in improving CAR-T cell therapy. The study will pave the way for further investigations focused on understanding and exploiting epigenetic mechanisms for immunotherapeutic outcomes

Reconnoitering the nexus between organizational culture and open innovation systems
Postmodern organizations strive to cultivate open innovation systems to foster product innovation and commercialization. Cultural dynamics can be a massive obstacle in flourishing the inbound and outbound open innovation in many organizations. However, little is known about the effect of different types of culture on the open innovation dimensions. This research aimed to investigate the role of cultural subtleties in nurturing inbound and outbound open innovation in the organizations. A quantitative research design was employed, and data were collected from a random sample of 231 managers from the automotive industry. Structural Equation Modeling (SEM) was used to test the hypotheses using Smart PLS. The results indicated that hierarchy culture, associated with formal rules and regulations, negatively affects the inbound and outbound open innovation. The Market culture has a positive relationship with inbound and outbound open innovation while adhocracy culture could positively impact the inbound open innovation only. On the other hand, clan culture has a negative effect on the outbound open innovation. We concluded that the organizational culture focused on internal integrations is more suitable for outbound open innovation, and the type of organizational culture focused on external differentiation is more likely to support inbound open innovation
Graves’ Disease: Pathophysiology, Genetics and Management
Graves’ disease is an autoimmune disorder in which hyperthyroidism (over active thyroid) is caused by the autoantibodies against the TSH receptor. It is mainly characterized by the appearance of goiter. The symptoms are wide ranging as thyroid hormone affects many body systems. It is common in women and in people with age below than 40. Graves’ disease is caused by a combination of genetic and environmental factors while genetics being the main cause. Graves’ disease is not a single gene defect but has a complex pattern of inheritance. Today it is clear that genetic predisposition to Graves’ disease is caused by multiple genes. HLA gene is one the most studied gene predisposing to Graves’ disease. Lot of polymorphisms in this gene has been to be associated with the disease. Lymphoid tyrosine phosphatase encoded by the gene PTPN22 has been found to increase the risk of many autoimmune diseases including Graves’ disease. The best documented association of PTPN22 variants to autoimmune disorders including GD is rs2476601 (C1858T). Other genes associated with the risk of GD are thyrotropin receptor (TSHR), thyroglobulin gene, FCRL3, SCGB3A2, and CTLA4. This chapter will discuss in detail the genetics, pathophysiology, diagnosis and treatment of Graves’ hyperthyroidism
