The Drosophila neuromuscular junction (NMJ) is an established model system used for the study of synaptic development and plasticity. The widespread use of the Drosophila motor system is due to its high accessibility. It can be analyzed with single-cell resolution. There are 30 muscles per hemisegment whose arrangement within the peripheral body wall are known. A total of 35 motor neurons attach to these muscles in a pattern that has high fidelity. Using molecular biology and genetics, one can create transgenic animals or mutants. Then, one can study the developmental consequences on the morphology and function of the NMJ. In order to access the NMJ for study, it is necessary to carefully dissect each larva. In this article we demonstrate how to properly dissect Drosophila larvae for study of the NMJ by removing all internal organs while leaving the body wall intact. This technique is suitable to prepare larvae for imaging, immunohistochemistry, or electrophysiology.

We describe and characterize a new species from the Singing honeyeater () in Western Australia, both morphologically and molecularly. Microscopic analysis of a fecal sample identified 25 ellipsoidal oocysts, measuring 21-25 × 18-20 μm (mean 23.4 × 18.

background: : Intravenous thrombolysis (IVT) for acute ischemic stroke (AIS) related to underlying intracranial artery dissection (IAD) poses potential risks, including the exacerbation of intramural hematoma and the rupture of the dissected arterial wall. However, the safety of IVT in this specific population remains uncertain.
aims:: This study aimed to assess whether IAD is associated with an increased risk of intracranial hemorrhage (ICH) following IVT and to evaluate its impact on functional outcomes.

Introduction: Patient engagement is continuously being promoted by patients as well as politicians and healthcare professionals. One way of increasing patient engagement is by using shared decision-making (SDM), which is a joint effort of clinicians and patients making decisions together.When planning stereotactic body radiation therapy (SBRT) for a lung tumour located close to the thoracic wall, there are conflicting interests between (1) delivering the highest possible dose to obtain local tumour control and (2) reducing the dose to the thoracic wall to decrease the risk of chest wall pain and rib fractures following treatment.

Yeast cell walls contain both classically-secreted and unconventionally-secreted proteins. The latter class lacks the signal sequence for translocation into the ER, therefore these proteins are transported to the wall by uncharacterized mechanisms. One such protein is the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) which is abundant in the cytosol, but also found in the yeast cell wall where it is enzymatically active.

The demand for female genital cosmetic surgery (FGCS) has significantly increased in recent years for two reasons: the advancement of surgical operations and the increased attention to women's esthetic and sexual well-being. Three authors independently analyzed different databases up to April 1, 2024. They selected the relevant data according to inclusion and exclusion criteria.
