Article Abstract
Neurodegenerative disorders of the central nervous system are a class of heterogeneous pathologies affecting millions of people worldwide and represent a global health burden in developed and developing countries. Without restorative treatments currently available, research on neuroprotective drugs is considered a health priority. In this study, new analogues of the glycyl-l-prolyl-l-glutamic acid (Glypromate) neuropeptide were designed, synthesized, and biologically evaluated using (1,3,4)-2-azanorbornane-3-carboxylic acid as a hybrid construct of l-proline and l-pipecolic acid. Neuroprotection assays carried out in human neuroblastoma SH-SY5Y cells using 6-hydroxydopamine as a stress inducer showed great percentage of recovery (29.7-40.0%) at 100 μM. Among this series, [(1,3,4)-2-glycyl-2-azanorbornane-3-carbonyl]-l-aspartic acid () stands out with a remarkable percentage of recovery (40.0%, at 100 μM) and safe toxicological profile in SH-SY5Y and human adipose mesenchymal stem cells.

Objectives: In this study, we examine the dynamics of birthing women relative to other family members in making caregiving decisions about postpartum maternal and infant care in four states in India. Specifically, we investigate the involvement of the father, maternal grandmother, and paternal grandmother of the newborn in household health decision-making.
Methods: We analyze data from 551 dyads of women with infants under six months and the family caregiver identified as providing the primary support in the postpartum period.

Introduction/aims: Therapeutic electrical stimulation (ES) of repaired nerves has been demonstrated to improve muscle function. Previous studies applied ES to the proximal transected nerve end (P-ES) with benefits to the neuronal cell body. We investigated whether a single ES dose applied to the distal end (D-ES) or distal and proximal ends (DP-ES) prior to nerve repair provides benefits to neuromuscular junction (NMJ) and muscle recovery.

Importance: Long COVID (ie, post-COVID-19 condition) is a substantial public health concern, and its association with health-related social needs, such as food insecurity, remains poorly understood. Identifying modifiable risk factors like food insecurity and interventions like food assistance programs is critical for reducing the health burden of long COVID.
Objective: To investigate the association of food insecurity with long COVID and to assess the modifying factors of Supplemental Nutrition Assistance Program (SNAP) participation and employment status.
