Instrument-Free Point-of-Care Diagnostic for Leishmania Parasites.

Background/objective: Leishmaniasis is the second deadliest parasitic disease in the world, after malaria, with an estimated 1.6 million new cases each year. While cutaneous leishmaniasis can result in permanent scars from lesions after treatment, the mucocutaneous and visceral diseases can result in life-altering and life-threatening complications.

Cleavable energy transfer labeled oligonucleotide probe for enhanced isothermal amplification detection and nano digital chip-based readout.

Quantitative analysis of human papillomavirus (HPV)-infected cervical cancer is essential for early diagnosis and timely treatment of cervical cancer. Here, we introduce a novel energy transfer-labeled oligonucleotide probe to enhance the loop-mediated isothermal amplification (LAMP) assay for highly sensitive and specific detection of HPV 16. Conducted as a single-step assay within a digital nanofluidic chip featuring numerous reaction reservoirs, our method facilitates target amplification under isothermal conditions.

Clinical Reasoning: A 63-Year-Old Man With Progressive Multicranial Neuropathy and Leptomeningeal Enhancement.

A 63-year-old man, with a history of melanoma and basal cell carcinoma, presented with progressive right-sided facial numbness, vertical diplopia, and headache. Brain MRI revealed leptomeningeal enhancement of multiple cranial nerves and an enhancing mass-like lesion along the anterolateral surface of the pons and midbrain. Subsequent brain biopsy demonstrated the final diagnosis.

A highly immunogenic UVC inactivated Sabin based polio vaccine.

Despite their efficacy, the currently available polio vaccines, oral polio vaccine (OPV) and inactivated polio vaccine (IPV), possess inherent flaws posing significant challenges in the global eradication of polio. OPV, which uses live Sabin attenuated strains, carries the risk of reversion to pathogenic forms and causing vaccine-associated paralytic poliomyelitis (VAPP) and vaccine-derived polio disease (VDPD) in incompletely vaccinated or immune-compromised individuals. Conventional IPVs, which are non-replicative, are more expensive to manufacture and introduce biohazard and biosecurity risks due to the use of neuropathogenic strains in production.

Adrenergic relaxations in an in situ urinary bladder model evoked by stimulation of sensory pelvic and pudendal nerves in the rat.

Urinary bladder dysfunction might be related to disturbances at different levels of the micturition reflex arc. The current study aimed to further develop and evaluate a split bladder model for detecting and analysing relaxatory signalling in the rat urinary bladder. The model allows for discrimination between effects at the efferent and the afferent side of the innervation.
