This paper describes the detection of Vesicular Stomatitis Virus using a novel capacitive immunosensor technology, whereby the respective antibodies for the antigens were used as a means for chemical detection on separate sensors. Devices were fabricated using standard etching and metal plating techniques, followed by immobilization of antibodies. Detection of antigen was performed by measuring voltage change due to changes in capacitance as antigen bound to the antibody surface. Capacitance changes were detected upon binding of specific antigen to the surface. This rugged, prototype device detected VSV down to the 2 pg/ml range.

Purpose: To present 4 family members with posterior polymorphous corneal dystrophy (PPCD), nonkeratoconic steep corneas, and myopia caused by a previously unknown genetic alteration in the ZEB1 gene.
Methods: Ophthalmic examinations and corneal curvature analyses were performed for all patients. Whole-exome targeted gene panel sequencing was performed for 1 patient.

The ubiquitin proteasome system (UPS) is implicated in protein homeostasis. One of the proteins involved in this system is HERC1 E3 ubiquitin ligase, which was associated with several processes including the normal development and neurotransmission at the neuromuscular junction (NMJ), autophagy in projection neurons, myelination of the peripheral nervous system, among others. The tambaleante (tbl) mouse model carries the spontaneous mutation Gly483Glu substitution in the HERC1 E3 protein.

Vacuole fusion is driven by SNARE proteins that require activation-or priming-by the AAA+ protein Sec18 (NSF) before they can bring membranes together and trigger the merger of two bilayers into a continuous membrane. Sec18 resides on vacuoles prior to engaging inactive cis-SNARE complexes through its interaction with the regulatory lipid phosphatidic acid (PA). Binding PA causes Sec18 to undergo large conformational changes that keeps it bound to the membrane, thus precluding its interactions with SNAREs.

Vesicle trafficking is pivotal in heparan sulfate (HS) biosynthesis, influencing its spatial and temporal regulation within distinct Golgi compartments. This regulation modulates the sulfation pattern of HS, which is crucial for governing various biological processes. Here, we investigate the effects of silencing Rab1A and Rab2A expression on the localisation of 3-O-sulfotransferase-5 (3OST5) within Golgi compartments and subsequent alterations in HS structure and levels.

Peccaries (collared peccary-CP-and white-lipped peccary-WLP) are an essential source of protein and income for rural communities in the Amazon region. Since 1980s, researchers in the Amazon have reported recurrent local disappearances of WLP populations. Although such disappearances impact the species conservation and the food security of rural societies, no studies have drawn consistent conclusions about the causes of these population collapses.
