Bauhinia forficata is a medicinal plant known as cow's paw, used for many purposes. Although there are studies that aimed to elucidate compounds from the plant leaves, there is no information about its polysaccharides. This study intended to obtain a polysaccharide rich fraction from its leaves, structurally characterize the water-soluble polysaccharides, as well as evaluate their effect on THP-1 cells.

Background: The findings of variants of uncertain significance (VUS) on a clinical genetic testing report pose a challenge for attending healthcare professionals (HCPs) in patient care. Here, we describe the outcomes of multidisciplinary VUS Rounds, implemented at a neurological disease tertiary care centre, which aid in interpreting and communicating VUS identified in our neurogenetics patient population.

Methods: VUS Rounds brought together genetic counsellors, molecular geneticists and scientists to evaluate VUS against genomic and phenotypic evidence and assign an internal temperature classification of 'VUS Hot', 'True VUS' or 'VUS Cold', corresponding to potential pathogenicity.

Patient satisfaction with synchronous telehealth care after strabismus surgery.

J AAPOS

December 2024

Ophthalmology Department, Hospital de Olhos do Paraná, Curitiba, Brazil; Department of Ophthalmology and Visual Sciences, Federal University of São Paulo, São Paulo, Brazil.

Background: To measure patient satisfaction with synchronous telehealth care, we administered the Telemedicine Satisfaction Questionnaire (TSQ) to assess the quality of care provided, its similarity to face-to-face meetings, and patients' perception of the interaction.

Methods: The Portuguese version of the TSQ was administered during 2022 to patients who received postoperative synchronous telehealth care after strabismus surgery in Curitiba, Brazil, from 2020 to 2022. The interval between the questionnaire application and teleconsultation ranged from 2 to 22 months after the telehealth encounter.

Members of the phospholipase D (PLD) superfamily found in Loxosceles spider venoms are potent toxins with inflammatory and necrotizing activities. They degrade phospholipids in cell membranes, generating bioactive molecules that activate skin cells. These skin cells, in turn, activate leukocytes involved in dermonecrosis, characterized by aseptic coagulative necrosis.

Vascular hamartoma is an abnormal development of endothelial tissue that rarely affects horses. Histopathological examination remains the gold standard for definitive diagnosis, yet the presence of abnormal vascular structures must be carefully differentiated from other vascular anomalies and neoplasms. This report describes two cases of vascular proliferation affecting the skin on the lateral side over the left tarsus and the dorsolateral region over the fetlock joint of two fillies.

Article Synopsis
  • Risk reduction salpingo-oophorectomy (RRSO) is a surgery often performed on women with hereditary breast and ovarian cancer (HBOC) syndrome caused by BRCA1 and BRCA2 mutations, which leads to surgical menopause and potential health risks.
  • A meta-analysis of six studies involving 1,320 patients examined the rates of cardiovascular and metabolic conditions post-surgery, including myocardial infarction, hypertension, hypercholesterolemia, and type 2 diabetes.
  • The results showed that while there were increased prevalence rates for conditions like hypertension (28%) and hypercholesterolemia (27.2%), the overall cardiovascular risk did not significantly increase for women undergoing RRSO.

Background: Heterotopic pregnancy and amniotic embolism are rare conditions that can be challenging to diagnose. To date, there are no cases of heterotopic pregnancy associated with amniotic embolism described in the literature. Therefore, we report the case of a pancreatic heterotopic pregnancy, which led to amniotic embolism and an unfavorable maternal outcome.

  • The study investigates whether naturally induced antibodies to HPV16 help prevent new infections in unvaccinated women, focusing on IgG, IgM, and neutralizing antibodies.
  • It found that women with higher levels of HPV16 IgG and neutralizing antibodies had a lower risk of newly detected infections, especially in younger women under 25.
  • The results suggest that while these antibodies may offer moderate protection, their effectiveness decreases with age, highlighting important considerations for public health strategies against HPV.

Modulation of starch-based film properties for encapsulation of microbial inoculant.

Int J Biol Macromol

December 2024

Nanotechnology National Laboratory for Agriculture (LNNA), Embrapa Instrumentation, São Carlos, SP 13560-970, Brazil; Graduate Program of Chemical Engineering, Federal University of São Carlos, São Carlos, SP 13565-905, Brazil. Electronic address:

Controlled release of beneficial microorganisms in agriculture by encapsulation in biopolymeric matrices can improve biofertilizer efficacy, but it requires the modulation of properties to ensure more efficient and predictable release patterns. This study investigated the effect of a starch-based system to protect and release Priestia megaterium (former Bacillus megaterium) processed as films modified with potential cell-protective additives (maltodextrin, cellulose, and bentonite). The release kinetics, physicochemical and morphological film characteristics, and their protection against UV (Ultraviolet) radiation and temperature were evaluated.

Mistletoes have higher hydraulic safety but lower efficiency in xylem traits than their hosts.

New Phytol

January 2025

CAS Key Laboratory of Tropical Forest Ecology, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Menglun, Mengla, 666303, Yunnan, China.

Both mistletoes and their hosts are challenged by increasing drought, highlighting the necessity of understanding their comparative hydraulic properties. The high transpiration of mistletoes requires efficient water transport, while high xylem tensions demand strong embolism resistance, representing a hydraulic paradox. This study, conducted across four environments with different aridity indices in Yunnan, China, examined the xylem traits of 119 mistletoe-host species pairs.

Herein, we introduce an unprecedented cascade reaction for the assembly of pyrrole-fused 1,5-benzodiazepine frameworks. These diverse privileged scaffolds were controllably constructed by intramolecular cyclization of β-enamino diketone, followed by annulation with -phenylenediamine. The protocol features efficient one-pot cascade cyclization/annulation, performed under simple and mild reaction conditions.
