Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land-cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity hotspot, especially for medium to large-sized species.

This article looks at how contemporary Italian films address issues of the tragedy and horror of domestic abuse and attempt to create a space for reflection and change. Ferzan Ozpetek's 2008, Andrès Arce Maldonado's 2017 Ivano De Matteo's (2016) () ultimately challenge the perception of domestic violence as a fixed and unchangeable condition for women. The films explore how female solidarity, empathy, and care can serve as pathways to combatting the isolation, guilt, and associated emotions that prevent women from seeking or finding .

In Brazil, most of the indexed studies on chiropterans date from 1954, with a slow and heterogeneous progress in the publication increasing. The aim of this study was to analyze the literature on bats in Brazil, identifying patterns, tendencies and knowledge gaps in the Brazilian federal states.

The basic idea is to integrate the actuation, sensing, and energy harvesting capabilities of the MFC patches in a SHM system operating in different regimes. As an example, during flight, under the effects of normal structural vibrations, the patches can work as energy harvesters by maintaining or restoring the battery charge of the stand-by SHM electronic board; on the other hand, if relevant/abnormal loadings are applied, or if local faults produce a noticeable stiffness variation of the monitored component, the patches can act as sensors for the power-up SHM board.

Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths.

Rare CYP27B1 mutations cause autosomal recessive vitamin D-dependent rickets type 1, and it has recently been reported that heterozygous CYP27B1 mutations are associated with increased MS susceptibility and lower active vitamin D levels.

In this study, we investigated the role of ATXN-2 in Italian patients clinically diagnosed with ALS and characterized the molecular structure of ATXN-2 expansions. We assessed the size of the CAG repeat in ATXN-2 exon 1 in 232 Italian ALS patients and 395 matched controls.

The objective of the current study was to evaluate the types of trauma and survival of patients that require immediate cardiopulmonary resuscitation in trauma emergencies. A total of 13301 patients treated as accident victims between July 2004 and December 2006 were evaluated in a prospective study.

Studies of Tpl2 knock-out mice reveal a clear defect in tumor necrosis factor-alpha production, although very little detail is known about its regulation and the signaling events involved. In the present study we demonstrated that phosphorylation of Cot was required for its maximal activity as phosphatase treatment of Cot decreased its kinase activity.

Introduction: A mouse strain lacking functional myotonic dystrophy protein kinase (DMPK) has recently been developed. DMPK-/- mice exhibit muscular and conduction abnormalities consistent with the disease; however, the site of abnormal cardiac conduction is unknown.
Methods And Results: Nine homozygous DMPK-/- mice and seven age matched wild-type (WT) controls underwent in vivo electrophysiologic studies using an endocardial 2-French catheter.
To evaluate the frequency, pattern, and severity of liver function test abnormalities in patients with Lyme disease associated with erythema migrans (EM), 115 individuals with no other identifiable cause for liver function test abnormalities who presented with EM between July 1990 and September 1993 were prospectively evaluated. For individuals with abnormal liver function tests, common causes of hepatitis, including hepatitis A, B, and C, were excluded. A local control group was used for comparison.

We focused on the effect of bacille Calmette-Guérin (BCG) vaccination on PPD skin test conversion because of changes in employee health service policies in 1990 regarding testing of persons who had received BCG vaccination.
Methods: The study took place in a university teaching hospital employee health service.
The growth of two strains of the "petite-negative" yeast Kluyveromyces lactis is inhibited by Tetracycline in different ways under the same culture conditions. Tetracycline resistant mutants of one strain have been isolated which can tolerate doses as high as 3000 microgram/ml of antibiotic. The segregation pattern of this character obtained by random spore analysis of the ascospores derived from the cross of the two strains strongly suggests that the resistance to tetracycline is under mitochondrial control.
