Introduction: Sarcoglycanopathies (LGMD 2C2F) are a subgroup of limb-girdle muscular dystrophies (LGMD), caused by mutations in sarcoglycan genes. They usually have a childhood onset and rapidly progressive course with loss of ability to walk over 12-16 years.

Methods: Next generation sequencing (NGS) targeted gene panel was performed in three adult patients with progressive muscle weakness in which routine muscle histology and immunohistochemistry were not diagnostic.

Results: Genetic analysis revealed homozygous or compound heterozygous mutations in SGCA gene and Western Blot demonstrated protein reduction confirming the diagnosis of α-sarcoglicanopathy.

Discussion: Our cases evidence that the diagnosis of mild forms of alfa sarcoglicanopathy could be a challenge and suggest the possibility that they could be underdiagnosed. The use of Next generation Sequencing targeted gene panels is very helpful in the diagnosis of these patients.

Heritable fragile bone disorders (FBDs), ranging from multifactorial to rare monogenic conditions, are characterized by an elevated fracture risk. Validating causative genes and understanding their mechanisms remain challenging. We assessed a semi-high throughput zebrafish screening platform for rapid in vivo functional testing of candidate FBD genes.

Hydrogen sulfide (H2S) plays crucial inflammatory modulating roles, representing a promising candidate for anti-inflammatory therapies. However, current H2S delivery approaches lack sufficient specificity against inflammatory response. Herein, regarding the overexpressed aminopeptidase N (APN) at the inflammation sites, an APN-activated self-immolative carbonyl sulfide (COS)/H2S donor (AlaCOS) was developed for inflammatory response-specific H2S delivery.

Background: Gallbladder neuroendocrine carcinoma (NEC) represents a subtype of gallbladder malignancies characterized by a low incidence, aggressive nature, and poor prognosis. Despite its clinical severity, the genetic alterations, mechanisms, and signaling pathways underlying gallbladder NEC remain unclear.

Case Summary: This case study presents a rare instance of primary gallbladder NEC in a 73-year-old female patient, who underwent a radical cholecystectomy with hepatic hilar lymphadenectomy and resection of liver segments IV-B and V.
