Body Condition of Reproductive and Non-Reproductive Broad-Snouted Caiman Females.

In this work, we calculated the body condition indices, K-Fulton and scaled mass index (SMI), of reproductive and non-reproductive adult females as an indication of stored energy. We considered 87 adult females captured from 2001 to 2018, both reproductive and non-reproductive. The body condition was calculated considering two scenarios: (a) only the weight of the female, and (b) the sum of the weight of the female and the average dry weight of her nest.

Caiman's fat enriched with n-3 fatty acids: potential food supplement.

Broad-snouted caiman (Caiman latirostris) products (meat, fat and oil) are currently beginning to be valued as a food of special interest due to its high content of n-3 fatty acids. Thus, the objective of this study was to characterize the fats of caiman fed with diets enriched with flaxseeds (Linus usitatissimun) rich in n-3 fatty acids, lignans and antioxidants. Caimans were fed six days a week with: a control diet (C), and a diet enriched with ground flaxseed = 90% C + 10% flaxseed ground (FS), during 30 (FS30) and 60 (FS60) days.

SAFETY AND EFFICACY OF THYMIC PEPTIDES IN THE TREATMENT OF HOSPITALIZED COVID-19 PATIENTS IN HONDURAS.

Coronavirus disease 2019 (Covid-19) active cases continue to demand the development of safe and effective treatments. This is the first clinical trial to evaluate the safety and efficacy of oral thymic peptides. ; We conducted a nonrandomized phase 2 trial with a historic control group to evaluate the safety and efficacy of a daily 250-mg oral dose of thymic peptides in the treatment of hospitalized Covid-19 patients.

Effect of flaxseed and flaxseed oil supplemented in caiman diet on meat fatty acids.

Increasing polyunsaturated or long-chain fatty acids in meat for human consumption improves both nutritional quality and consumer perception. The increase could occur through the addition of rich sources of omega-3 fatty acids (such as flaxseed or flaxseed oil) to the animal diet. The aim of this study was to evaluate the effects of dietary supplement with two presentations of flax (crushed seeds or oil) on the change of FA content in two cuts of caiman meat (tail and neck).

Genital anatomy and copulatory interactions in the broad snouted Caiman (Caiman latirostris).

The broad snouted caiman is a crocodylian native to South America that is subject to extensive conservation management in both wild and farming environments. Although reproductive behaviors like egg laying and clutch care have been examined in this species, little else is known about their copulatory system. We examined the anatomy of male and female cloacal and genital tissues ex vivo to build hypotheses of their interactions during copulation and the effects of that interaction on insemination.

"Intracascaral space" an eggshell structure of Caiman latirostris eggs.

In recent decades, eggshells of eggs from large-bodied reptiles have been studied by many researchers, to describe the eggshell, to compare them to extinct lineages that once inhabited our planet and also to understand how the egg provides the embryo specific conditions during incubation. In previous studies we described and characterized normal and pathologic Caiman latirostris eggshells; we also evaluated how the eggshell changes during incubation. In a study relating temperature variation and eggshell structures of successful eggs, we observed empty structures not previously described that we termed "intracascaral space".

Human Pasteurella multocida Infection with Likely Zoonotic Transmission from a Pet Dog, Spain.

We report a case of urinary tract infection caused by an unusual genotype (sequence type 211) of Pasteurella multocida associated with human infection. Molecular genetic analysis of P. multocida isolates obtained from the human patient and his pet strongly suggests a zoonotic transmission of this bacterium.

Size of nesting female Broad-snouted Caimans (Caiman latirostris Daudin 1802).

The southern distribution of the Broad-snouted Caiman (Caiman latirostris Daudin 1802) in Argentina occurs in Santa Fe Province, where its population has been under management by "Proyecto Yacaré" since 1990. From 1997 to 2016, we captured 77 nesting female Broad-snouted Caimans in Santa Fe Province. Our results suggest that previously defined size classes for Broad-snouted Caiman do not adequately describe the reproductively mature female segment of the population.

There is no association between the presence of anti-thyroid antibodies and increased reproductive loss in pregnant women after ART: a systematic review and meta-analysis.

Women submitted to ART treatments represent a select subgroup of individuals. Several studies have described the relationship between TAI and pregnancy outcomes as a result of ART, with contradictory results. The purpose of this systematic review was to determine the association between TAI and the risk of miscarriage in pregnancies resulting from ART.

Eggshell structure in eggs improves embryo survival during nest inundation.

Egg inundation often results in poor hatching success in crocodylians. However, how tolerant eggs are to submergence, and/or how eggshell ultrastructure may affect embryo survival when inundated, are not well understood. In this study, our objective was to determine if embryo survival in is affected by eggshell surface roughness, when eggs are submerged under water.

Negative core affect and employee silence: How differences in activation, cognitive rumination, and problem-solving demands matter.

Employees can help to improve organizational performance by sharing ideas, suggestions, or concerns about practices, but sometimes they keep silent because of the experience of negative affect. Drawing and expanding on this stream of research, this article builds a theoretical rationale based on core affect and cognitive appraisal theories to describe how differences in affect activation and boundary conditions associated with cognitive rumination and cognitive problem-solving demands can explain employee silence. Results of a diary study conducted with professionals from diverse organizations indicated that within-person low-activated negative core affect increased employee silence when, as an invariant factor, cognitive rumination was high.

Hormonal pretreatment preserves liver regenerative capacity and minimizes inflammation after partial hepatectomy.

Introduction: The treatment of brain dead donors with combined hormonal resuscitation protocols, including methylprednisolone (MP) and triiodothyronine (T3), among others, was developed to increase the viability and function of transplanted organs, primarily heart and lung. Even when it has regarded successful results in term of donors and organs recovery, its effects over specific parameters in organs like the liver are unknown.

Material And Methods: Male Sprague-Dawley rats were pretreated with MP (0.

Genotyping Chlamydia trachomatis strains among men who have sex with men from a Northern Spain region: a cohort study.

Objectives: To determine the prevalence of anorectal Chlamydia trachomatis serovars in a group of men who have sex with men (MSM) with high risk sexual behaviour, attendees at a sexually transmitted infection (STI) unit from a region in Northwest Spain.

Design: Retrospective and descriptive study of all swabs obtained from all MSM attendees at an STI unit, from 2007 to 2011. Retrospective ethical approval was granted by the Ethical Regional Committee of Clinical Investigation of the Principality of Asturias.

Accuracy of ocular axial length measurement with MRI.

Background: This study assessed axial length measurements taken with MRI compared to A-scan ultrasonography for use in silicone-filled eyes with cataracts.

Methods: This study was a double-blinded prospective comparison study of axial length measurements made by MRI and A-scan ultrasonography. MRI scans of 20 patients undergoing MRI were reviewed to determine axial length.

Imaging of liver disease: comparison between quadruple-phase multidetector computed tomography and magnetic resonance imaging.

Background And Aim: To compare quadruple-phase multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) for the assessment of focal and diffuse liver disease.

Methods: Quadruple-phase contrast-enhanced MDCT and MRI of 37 consecutive patients were retrospectively reviewed by two readers (R1 and R2). In patients with focal liver lesions, the gold standard was histopathology (n = 17) and/or long-term (>6 months) follow-up imaging (n = 27) or transarterial chemoembolization (n = 1).

Prevalence of X4 tropic viruses in patients recently infected with HIV-1 and lack of association with transmission of drug resistance.

Background: HIV-1 co-receptor usage may play a critical role in AIDS pathogenesis. Information on viral tropism in HIV-1 seroconverters is scarce, as is the relationship with transmission of drug-resistant viruses.

Methods: All consecutive HIV-1 seroconverters seen between January 1997 and December 2005 in 17 Spanish hospitals were retrospectively analysed.

Assessment of a new approach for the two-electron cumulant in natural-orbital-functional theory.

The Piris natural orbital functional (PNOF) based on a new approach for the two-electron cumulant has been used to predict adiabatic ionization potentials, equilibrium bond distances, and harmonic vibrational frequencies of 18 diatomic molecules. Vertical ionization potentials have been calculated for the same set of diatomic molecules and another set of 20 polyatomic molecules using energy-difference methods as well as the extended Koopman theorem. The PNOF properties compare favorably with the coupled-cluster-doubles results.

Resistance to nonnucleoside reverse-transcriptase inhibitors and prevalence of HIV type 1 non-B subtypes are increasing among persons with recent infection in Spain.

The prevalence of drug resistance mutations was 12.1% among 198 persons who experienced human immunodeficiency virus (HIV) seroconversion identified in Spain during 1997-2004. There was a significant increase of K103N and of non-B subtypes over time.

Antiretroviral recommendations may influence the rate of transmission of drug-resistant HIV type 1.

Background: Human immunodeficiency virus (HIV) treatment guidelines have evolved, shifting from more-aggressive to more-conservative approaches. The potential impact of these shifts on the transmission of drug-resistant virus is unknown.

Methods: Drug-resistance genotypes were examined in all consecutive patients with recent HIV type 1 (HIV-1) seroconversion (hereafter, "HIV-1 seroconverters") seen at 10 Spanish hospitals since 1997.

Prevalence of hepatitis C virus infection in the general population of northern Spain.

Objectives: To estimate the prevalence of hepatitis C in a population of northern Spain and describe (i) the risk factors associated with infection and (ii) the distribution of genotypes.

Design: Randomized cross-sectional study.

Methods: A random sample of 1,170 people participated in the study.

Epidemiological, clinical and biological characteristics of acute non-A, non-B hepatitis with and without hepatitis C virus infection.

Serially collected serum samples from 81 patients with acute non-A, non-B hepatitis were tested for the presence of antibodies to hepatitis C virus (anti-HCV) by a second-generation enzyme immunoassay (EIA) test. Anti-HCV was detected in 56 cases (69%) during the first month, in 61 cases (75%) at 3 months and in 63 cases (78%) at 6 months. In those 18 patients showing anti-HCV negative results in the three determinations, hepatitis C virus (HCV) RNA was tested using a nested polymerase chain reaction (PCR) in the first serum sample and was detected in only one case.
