Nanostructured lipid carriers for enhanced batimastat delivery across the blood-brain barrier: an in vitro study for glioblastoma treatment.

Glioblastoma presents a significant treatment challenge due to the blood-brain barrier (BBB) hindering drug delivery, and the overexpression of matrix metalloproteinases (MMPs), which promotes tumor invasiveness. This study introduces a novel nanostructured lipid carrier (NLC) system designed for the delivery of batimastat, an MMP inhibitor, across the BBB and into the glioblastoma microenvironment. The NLCs were functionalized with epidermal growth factor (EGF) and a transferrin receptor-targeting construct to enhance BBB penetration and entrapment within the tumor microenvironment.

Eco-epidemiological analysis of Rickettsia parkeri in domestic dogs and Amblyomma ovale ticks in the Atlantic rainforest of Northeast Brazil.

In Brazil, spotted fever (SF) is caused by two species of Rickettsia, both of which are transmitted by Amblyomma ticks: Rickettsia rickettsii, which results in severe and often fatal cases, and Rickettsia parkeri, which causes a mild illness. This study focused on R. parkeri in Amblyomma ovale ticks from the Maciço de Baturité region, Ceará, Northeast Brazil, an area endemic for SF with mild symptoms.

Changes in Postpartum Opioid Prescribing After Implementation of State Opioid Prescribing Limits.

Importance: In response to the growing opioid crisis, states implemented opioid prescribing limits to reduce exposure to opioid analgesics. Research in other clinical contexts has found that these limits are relatively ineffective at changing opioid analgesic prescribing.

Objective: To examine the association of state-level opioid prescribing limits with opioid prescribing within the 30-day postpartum period, as disaggregated by type of delivery (vaginal vs cesarean) and opioid naivete.

The Influence of Fatty Acid Oxygenases PpoA and PpoC on Caspofungin Susceptibility.

can cause invasive pulmonary aspergillosis (IPA). Fungicidal azoles and fungistatic caspofungin (CAS) are the first- and second-line therapies, respectively, used to treat IPA. Treatment of with CAS or micafungin induces the production of the oxylipin 5,8-diHODE by the fungal oxygenase PpoA.

Occurrence of Babesia and Anaplasma in ruminants from the Catimbau National Park, Semiarid Region of Northeast Brazil.

Babesiosis and Anaplasmosis are diseases associated with economic losses; ticks and blood-sucking flies are important zoonotic vectors and reservoirs. This study aimed to investigate the presence of anti-Babesia spp. and anti-Anaplasma marginale antibodies using enzyme-linked immunosorbent assay (ELISA), in ruminants at the Catimbau National Park.
