There is a strong evidence supporting the hypothesis of synaptic dysfunction as a major contributor to neural circuit and network disruption underlying emotional and mood dysregulation in psychiatric disorders(Simmons et al.,2024).Diverse sets of distinct molecular signaling pathways converge on the synapse to regulate synaptogenesis,synaptic function,and synaptic plasticity in brain regions and circuits through complex interactions organized by numerous multivalent protein scaffolds,including the family of proteins known as A-kinase anchoring proteins(AKAPs).

Congenital buried penis is an uncommon urological anomaly affecting approximately 0.3%of young children.1 Buried penis occurs when a normal-length penis appears to be externally small,and congenital forms are associated with poor attachment between the penile base and skin,inelastic dartos fascia,inadequate outer penile skin,or excess suprapubic fat deposition.

Therapeutic proteins and peptides have revolutionized treatment for a number of diseases, and the expected increase in macromolecule-based therapies brings a new set of challenges for the pharmaceutics field. Due to their poor stability, large molecular weight, and poor transport properties,therapeutic proteins and peptides are predominantly limited to parenteral administration. The short serum half-lives typically require frequent injections to maintain an effective dose, and patient compliance is a growing issue as therapeutic protein treatments become more widely available. A number of studies have underscored the relationship of subcutaneous injections with patient non-adherence, estimating that over half of insulin-dependent adults intentionally skip injections. The development of oral formulations has the potential to address some issues associated with non-adherence including the interference with daily activities, embarrassment, and injection pain. Oral delivery can also help to eliminate the adverse effects and scar tissue buildup associated with repeated injections. However, there are several major challenges associated with oral delivery of proteins and peptides, such as the instability in the gastrointestinal(GI)tract, low permeability, and a narrow absorption window in the intestine. This review provides a detailed overview of the oral delivery route and associated challenges. Recent advances in formulation and drugdelivery technologies to enhance bioavailability are discussed, including the co-administration of compounds to alter conditions in the GI tract, the modification of the macromolecule physicochemical properties, and the use of improved targeted and controlled release carriers.

Acute-on-chronic liver failure(ACLF) results from an acute insult that occurs in patients with chronic liver disease,ultimately leading to liver *** underlying chronic liver dysfunction can be characterized into three categories:chronic liver disease with no cirrhosis;compensated liver cirrhosis;decompensated *** underlying chronic liver diseases are numerous and include alcoholic liver disease,viral hepatitis(types B and C),nonalcoholic fatty liver disease,and other underlying etiologies.1 Acute liver injury can arise from viral hepatitis infections(types A,B,and E),acetaminophen toxicity,drug-induced liver injury,toxin exposure,and numerous other hepatic and extrahepatic causes including heat stroke.2 Due to the numerous aspects of pathology that can generate both the chronic and acute components of ACLF,these patients can have significantly different pathology *** makes ACLF difficult to clas-sify,and this is evident by the different ACLF definitions being used by the Asian Pacific Association for the Study of the Liver,the European Association for the Study of the Liver–Chronic Liver Failure Consortium,and the North American Consortium for the Study of End-Stage Liver Disease with regards to mor-tality,presence of organ failure,inclusion/exclusion criteria,and other disease characteristics.3,4 In addition,these differ-ent definitions of ACLF,depending on which definition is used,could potentially influence the outcomes of studies depending upon the metric investigated.
