Patterns of single limb forces during terrestrial and arboreal locomotion in rosy-faced lovebirds (Psittaciformes: Agapornis roseicollis).

The biomechanical demands of arboreal locomotion are generally thought to necessitate specialized kinetic and kinematic gait characteristics. While such data have been widely collected across arboreal quadrupeds, no study has yet explored how arboreal substrates influence the locomotor behavior of birds. Parrots - an ancient arboreal lineage that exhibit numerous anatomical specializations towards life in the trees - represent an ideal model group within which to examine this relationship.

Locomotor energetics in the Indonesian blue-tongued skink (Tiliqua gigas) with implications for the cost of belly-dragging in early tetrapods.

During the last decade, biomechanical and kinematic studies have suggested that a belly-dragging gait may have represented a critical locomotor stage during tetrapod evolution. This form of locomotion is hypothesized to facilitate animals to move on land with relatively weaker pectoral muscles. The Indonesian blue-tongued skink (Tiliqua gigas) is known for its belly-dragging locomotion and is thought to employ many of the same spatiotemporal gait characteristics of stem tetrapods.

Adverse events of fecal microbiota transplantation: a meta-analysis of high-quality studies.

Background: Fecal microbiota transplantation (FMT) has shown excellent efficacy in treating infection, as well as promise in several other diseases. The heightened interest is accompanied by concerns over adverse events (AE) and safety. To further understand that in FMT, we performed a systematic review of the literature and a meta-analysis of high-quality, prospective randomized controlled trials FMT.

Vedolizumab Dose Escalation Improves Therapeutic Response in a Subset of Patients with Ulcerative Colitis.

Background: The Gemini trial failed to detect a significant difference in response rate for patients with ulcerative colitis (UC) randomized to standard (every 8 week) vedolizumab dosing vs escalated (every 4 week) dosing. Subsequent real-world data imply the Gemini trial design may have obscured a benefit of escalated dosing.

Aims: We investigated outcomes after vedolizumab dose escalation for patients with UC.

Laboratory Testing Methods for Novel Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2).

Following the first reports of coronavirus disease-19 (COVID-19) by China to the World Health Organization (WHO) on 31st December 2019, more than 4,302,774 novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) cases have been reported by authorities in 212 countries and territories by 12th May 2020. The outbreak and spread of COVID-19 worldwide, highlights the critical need for developing rapid and accurate diagnostic testing methods for emerging human coronavirus (CoV) infections. Testing is crucial to track the spread of disease during a pandemic, and to swiftly permit public health interventions including isolation, quarantine, and appropriate clinical management of afflicted individuals.

Not in our community: Queer women challenge religious homophobia in rural Kentucky.

"Not in my backyard" (NIMBY) movements emerge when a social or political event spurs opposition from local residents. Much research on NIMBY movements concentrates on local residents' efforts to defend their community from unwanted "outsiders" or elements, such as a waste incinerator or sex offenders. Little is written on how NIMBY activism can redefine a place to be more inclusive of sexual minorities and supportive of progressive social initiatives.

p27/Kip1 functions as a tumor suppressor and oncoprotein in osteosarcoma.

The p27/kip1 (p27) tumor suppressor inhibits cyclin/cyclin-dependent kinase (CDK) complexes and halts cell cycle progression. p27 further regulates invasion and migration in cancer cells, suggesting p27 also functions as an oncoprotein. Using a human osteosarcoma tissue microarray we identified high expression of cytoplasmic p27 in metastatic tumors.

Glutamine Hydrolysis by Imidazole Glycerol Phosphate Synthase Displays Temperature Dependent Allosteric Activation.

The enzyme imidazole glycerol phosphate synthase (IGPS) is a model for studies of long-range allosteric regulation in enzymes. Binding of the allosteric effector ligand N'-[5'-phosphoribulosyl)formimino]-5-aminoimidazole-4-carboxamide-ribonucleotide (PRFAR) stimulates millisecond (ms) timescale motions in IGPS that enhance its catalytic function. We studied the effect of temperature on these critical conformational motions and the catalytic mechanism of IGPS from the hyperthermophile in an effort to understand temperature-dependent allostery.

Pursuing Social Justice through Public Health: Gender and Sexual Diversity Activism in Malawi.

African lesbian, gay, bisexual, transgender, intersex, and queer (LGBTIQ) organizations face various strategic dilemmas in contexts characterized by political hostility to gender and sexual dissidents. In Malawi, one such context, we examine how an LGBTIQ social movement organization (SMO) in Malawi, the Centre for the Development of People (CEDEP), navigated one particular strategic dilemma-the dilemma of whether to adopt a less politicized public-health approach or a more nimble, grassroots-oriented, and social-justice approach to their advocacy work-and the consequences of the organization's strategic decisions. Scholars interpret these approaches as signifying differential political engagement among organizations, with the social-justice approach indicating political engagement and the public-health approach signaling political disengagement.

"Lesbian"/female same-sex sexualities in Africa.

Understandings of African lesbian sexualities have been affected by silence, repression, and uncertainty. The subject of lesbian experiences and sexualities in Africa constitutes an opportunity for feminist scholars to address the transnational politics of knowledge production about African lesbians' lives and the contours of lesbian art, activism, and relationships in African nations. This article contextualizes the state of research on African lesbian sexualities and introduces the special issue.

Breast arterial calcifications (BACs) found on screening mammography and their association with cardiovascular disease.

Objective: Breast arterial calcifications (BACs) are common but unreported findings on screening mammograms. This study correlated mammographically detected BACs with coronary artery disease (CAD) risk factors and a history of atherosclerotic cardiovascular disease (ASCVD), estimating the relative risk of ASCVD in patients with BACs.

Design: Women arriving for breast cancer screening mammography gave their consent to complete a questionnaire and to allow their mammograms to be analyzed independently for the presence of BACs by certified radiologists, who were blinded to the results of the questionnaire.

Hormonal therapy is associated with a lower prevalence of breast arterial calcification on mammography.

Objective: To bring further understanding to the relationship between hormonal therapy (HT) and breast arterial calcification (BAC).

Methods: Of women arriving for breast cancer screening mammography, 1995 consented to complete a survey and have their mammograms analyzed for the presence of BAC. The survey assessed HT use and major risk factors for CAD.

Benign versus malignant breast masses: optical differentiation with US-guided optical imaging reconstruction.

Purpose: To investigate prospectively the feasibility of using optical tomography with ultrasonographic (US) localization to differentiate malignant from benign breast masses and to compare optical tomography with color Doppler US.

Materials And Methods: The study was approved by the local internal review board committee and by the Human Subjects Research Review Board of Army Medical Research and Materiel Command. Signed informed consent was obtained, and the study was HIPAA compliant.

Plasminogen directs the pleiotropic effects of uPA in liver injury and repair.

The urokinase-type plasminogen activator (uPA) plays a central role in liver repair. Nevertheless, the hepatic overexpression of uPA results in panlobular injury and neonatal mortality. Here, we define the molecular mechanisms of liver injury and explore whether uPA can regulate liver repair independently of plasminogen.

Fine needle aspiration cytology diagnosis of renal medullary carcinoma: a case report.

Background: Renal medullary carcinoma is a recently described, highly aggressive neoplasm that affects predominantly young African American males with a history of sickle cell trait. To the best of our knowledge, this is the first report of fine needle aspirate cytology (FNAC) findings of renal medullary carcinoma.

Case: A 14-year-old, African American male with a history of sickle cell trait presented with the sudden onset of third cranial nerve palsy.

Plasminogen activators direct reorganization of the liver lobule after acute injury.

Tissue repair requires an adequate cellular proliferation coordinated with the timely proteolysis of matrix elements. Based on the properties of plasminogen activators in liver cell proliferation and tissue proteolysis, we explored the regulatory role of tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA) in liver repair. Using carbon tetrachloride (CCl(4)) intoxication as a model of acute liver injury, we found that tPA-deficient mice displayed a mild defect in hepatic repair, whereas livers of uPA-deficient mice had a more substantial delay in repair, with injury of centrilobular hepatocytes persisting up to 14 days after CCl(4).

Tumor necrosis factor-alpha and lipopolysaccharide enhance interferon-induced antichlamydial indoleamine dioxygenase activity independently.

In macrophages, interleukin-1 (IL-1) and lipopolysaccharide (LPS) enhance the antichlamydial effect of interferon-gamma (IFN-gamma) by increasing indoleamine 2,3-dioxygenase (IDO) activity in a dose-dependent manner. Our objectives were to characterize the antichlamydial effect of tumor necrosis factor-alpha (TNF-alpha) on IFN-induced IDO activity and to establish the relationship between LPS and TNF-alpha in IDO potentiation. TNF-alpha inhibited chlamydial growth in a dose-dependent manner only in IFN-treated macrophages.
