Route Planning Process by the Endangered Black Lion Tamarin in Different Environmental Contexts.

Daily, primates take a variety of decisions to establish why, when, and where to move. However, little is known about the factors influencing and shaping primate daily routes. We investigated the decision-making processes linked to route planning in four groups of black lion tamarins (BLT-Leontopithecus chrysopygus).

Encouraging news for in situ conservation: Translocation of salamander larvae has limited impacts on their skin microbiota.

The key role of symbiotic skin bacteria communities in amphibian resistance to emerging pathogens is well recognized, but factors leading to their dysbiosis are not fully understood. In particular, the potential effects of population translocations on the composition and diversity of hosts' skin microbiota have received little attention, although such transfers are widely carried out as a strategy for amphibian conservation. To characterize the potential reorganization of the microbiota over such a sudden environmental change, we conducted a common-garden experiment simulating reciprocal translocations of yellow-spotted salamander larvae across three lakes.

Use of front face fluorescence spectroscopy coupled with multivariate data analysis for monitoring biscuits' quality during aging.

In this study, the potentiality of front face fluorescence spectroscopy (FFFS) for the evaluation of the quality of biscuits manufactured with butylated hydroxytoluene and pomegranate peel extract during aging was investigated. By using the principal component analysis, vitamin A and tryptophan spectra allowed a clear discrimination between biscuit samples according to the nature of antioxidants, while fluorescent Maillard reaction products spectra showed clear differentiation between samples according to the storage time. Clear differentiation between biscuits according to the used antioxidants and storage time was achieved by using common components and specific weights analysis.

The New 2021 CKD-EPI Equation Without Race in a European Cohort of Renal Transplanted Patients.

Background: Whether the new chronic kidney disease-epidemiology (CKD-EPI) equation without the race variable remains accurate enough for glomerular filtration rate (GFR) estimation in non-US kidney transplant recipients (KTRs) is unclear. We sought to compare the predictive performance between this equation and the classical CKD-EPI equation in a French cohort of KTRs. We also evaluated the performance of the European Kidney Function Consortium (EKFC) equation, an estimate that has proved very accurate in nontransplant patients and that does not include race variable.

At the Peak of the Second Wave of COVID-19, Did Millennials Show Different Emotional Responses from Older Adults?

The COVID-19 pandemic disturbs mental health. Indeed, higher levels of negative emotions and anxiety, along with lower levels of positive emotions and well-being, have been highlighted. As a result, individuals need to regulate these psychological states in a context of uncertainty and daily restrictions (e.

COVID-19 and Its Lockdown in Belgium: How Limited Access to Environmental Satisfaction Impacts Emotions?

The COVID-19 pandemic has been shown to induce several psychological consequences (e.g., increases in anxiety and stress).

Hepatitis C in Lebanon: the burden of the disease and the value of comprehensive screening and treatment.

Purpose: To analyze the hepatitis C virus (HCV) burden in Lebanon and the value of comprehensive screening and treatment for different age groups and fibrosis stages.

Methods: We used a multicohort, health-state-transition model to project the number of HCV genotype 1 and 4 patients achieving a sustained virologic response 12 weeks after treatment or progressing to compensated cirrhosis (CC), decompensated cirrhosis (DCC), hepatocellular carcinoma (HCC), or liver-related death (LrD) from 2016 to 2036. In the low/medium/high screening scenarios, the proportion of patients screened for HCV was projected to increase to 60%/85%/99%, respectively, by 2036.

Giant morphea-form basal cell carcinoma of the umbilicus: Successful debulking with vismodegib.

Basal cell carcinoma of the umbilicus is very rare. The nodular subtype is the main representative. Giant basal cell carcinomas represent around 1% of all basal cell carcinomas.

Depth-specific fluctuations of gene expression and protein abundance modulate the photophysiology in the seagrass Posidonia oceanica.

Here we present the results of a multiple organizational level analysis conceived to identify acclimative/adaptive strategies exhibited by the seagrass Posidonia oceanica to the daily fluctuations in the light environment, at contrasting depths. We assessed changes in photophysiological parameters, leaf respiration, pigments, and protein and mRNA expression levels. The results show that the diel oscillations of P.

Prevention of Incisional Hernias by Prophylactic Mesh-augmented Reinforcement of Midline Laparotomies for Abdominal Aortic Aneurysm Treatment: A Randomized Controlled Trial.

Background: The incidence of incisional hernias after abdominal aortic aneurysm repair is high. Prophylactic mesh-augmented reinforcement during laparotomy closure has been proposed in patients at high risk of incisional hernia.

Methods: A multicenter randomized trial was conducted on patients undergoing elective abdominal aortic aneurysm repair through a midline laparotomy (Clinical.

Recurrent in situ melanoma successfully treated with ingenol mebutate.

Background: Treatment options for melanoma in situ (MIS) include imiquimod, radiation therapy, cryotherapy, excisional and Mohs surgery. Ingenol mebutate is a new topical treatment option recognized for actinic keratosis. Although in vitro effectiveness has been demonstrated on melanoma cell lines, its therapeutic potential for in vivo melanomas is unknown.

Early infantile cardiomyopathy and liver disease: a multisystemic disorder caused by congenital lipodystrophy.

Congenital generalized lipodystrophy is a rare inherited multisystemic disorder associated with disturbances of adipocyte functions. We report a young boy presenting at age 1 month with liver disease and severe hypertrophic cardiomyopathy. Despite this multisystemic involvement and contrasting with a cachectic appearance, the anthropometric parameters showed marked overgrowth (+4 DS), leading to diagnosis of congenital lipodystrophy, which was confirmed by the presence of the new homozygous c.

Importance of PIKKs in NF-κB activation by genotoxic stress.

Alteration of the genome integrity leads to the activation of a vast network of cellular responses named "DNA damage response". Three kinases from the phosphoinositide 3-kinase-like protein kinase family regulate this network; ATM and DNA-PK both activated by DNA double-strand breaks and ATR activated by replication blocks. "DNA damage response" pathway coordinates cell cycle arrest, DNA repair, and the activation of transcription factors such as p53 and NF-κB.

Mixed origin of neovascularization of human endometrial grafts in immunodeficient mouse models.

Background: In vivo mouse models have been developed to study the physiology of normal and pathologic endometrium. Although angiogenesis is known to play an important role in endometrial physiology and pathology, the origin of neovasculature in xenografts remains controversial. The aim of this study was to assess the origin of the neovasculature of endometrial grafts in different mouse models.

Development of an animal experimental model to study the effects of levonorgestrel on the human endometrium.

Background: This study was designed to develop an animal model to test the response of endometrium to local progestin delivery.

Methods: Proliferative human endometrium was subcutaneously grafted in two groups of SCID mice that received, 2 days before, a subcutaneous estradiol (E(2)) pellet and, for half of them, an additional implant of levonorgestrel (LNG). Mice were sacrificed 1, 2, 3 or 4 weeks after endometrial implantation and grafts were histologically analysed.

Endometrial vessel maturation in women exposed to levonorgestrel-releasing intrauterine system for a short or prolonged period of time.

Background: Levonorgestrel-releasing intrauterine system (LNG-IUS), although inserted to reduce heavy menstruation, causes irregular early transient bleeding. The objective of the study was to document quantitative changes in endometrial vessels of short- (< or =3 months) and long-term (> or =12 months) LNG users. The area, density and maturation of endometrial vessels were quantified in 19 endometrial biopsies of women with LNG-IUS and in 10 normally ovulating patients during mid-luteal phase.

Differential involvement of the hMRE11/hRAD50/NBS1 complex, BRCA1 and MLH1 in NF-kappaB activation by camptothecin and X-ray.

Camptothecin (CPT) and X-ray (XR) generate double-strand breaks (DSB) that can be processed by homologous or nonhomologous recombination. We studied the participation of proteins involved in recombination pathways and cell cycle control in the signal transduction between DNA damage and NF-kappaB. Cells harbouring mutated NBS, hMRE11, BRCA1 or MLH1 were analysed.
