Validation of morphological ear classification devised by principal component analysis using three-dimensional images for human identification.

This study attempts to classify ear morphology for human identification in forensic investigations by distinguishing between the upper auricle and lobule areas. A three-dimensional homologous model of the ear was created using 414 ear images of males aged 17-93 years reconstructed from computed tomography scans of forensic autopsy cases. Morphological changes were visualized using principal component analysis and areas of significant individual differences within the entire ear were identified.

Integrating Biocatalysts into Metal-Organic Frameworks: Disentangling the Roles of Affinity, Molecular Weight, and Size.

The integration of biocatalysts within metal-organic frameworks (MOFs) is attracting growing interest due to its potential to both enhance biocatalyst stability and sustain biocatalyst activity in organic solvents. However, the factors that facilitate the post-synthetic infiltration of such large molecules into MOF pores remain unclear. This systematic study enabled the identification of the influence of biocatalyst molecular size, molecular weight and affinity on the uptake by an archetypal MOF, NU-1000.

The Management of Two Cases with Retinal Arterial Macroaneurysm by Anti-Vascular Endothelial Growth Factor.

Case Presentation: Case 1 involved a 71-year-old woman with a 30-year history of diabetes who was undergoing dialysis. Pretreatment visual acuity in the right eye was 0.

Typhoid conjugate vaccine perceptions and coverage among children and adults: Findings from a post-campaign coverage survey - Harare, Zimbabwe, 2019.

Background: In 2019, following a large outbreak of typhoid fever, the Zimbabwe Ministry of Health and Child Care conducted a typhoid conjugate vaccine (TCV) vaccination campaign in nine high-risk suburbs of Harare. We aimed to evaluate TCV vaccination coverage, vaccine perceptions, and adverse events reported after vaccination.

Methods: We conducted a two-stage cluster survey to estimate vaccination coverage in the campaign target areas among children aged 6 months-15 years and to classify coverage as either adequate (≥75 % coverage) or inadequate (<75 % coverage) among adults aged 16-45 years in one suburb.

Missed opportunities for TB diagnostic testing among people living with HIV in Zimbabwe: Cross-sectional analysis of the Zimbabwe Population-based HIV Impact Assessment (ZIMPHIA) survey 2015-16.

Background: Using data from the Zimbabwe Population-based HIV Impact Assessment survey 2015-2016, we examined the TB care cascade and factors associated with not receiving TB diagnostic testing among adult PLHIV with TB symptoms.

Methods: Statistical Analysis was limited to PLHIV aged 15 years and older in HIV care. Weighted logistic regression with not receiving TB testing as outcome was adjusted for covariates with crude odd ratios (ORs) with p < 0.

Reversible Influence of Hemipiperazine Photochromism on the Early Development of Zebrafish Embryo.

This study explores the potential of controlling organismal development with light by using reversible photomodulation of activity in bioactive compounds. Specifically, our research focuses on plinabulin 1, an inhibitor of tubulin dynamics that contains a photochromic motif called hemipiperazine. The two isomeric forms, Z-1 and E-1, can partially interconvert with light, yet show remarkable thermal stability in darkness.

Caveolae disassemble upon membrane lesioning and foster cell survival.

Repair of lesions in the plasma membrane is key to sustaining cellular homeostasis. Cells maintain cytoplasmic as well as membrane-bound stores of repair proteins that can rapidly precipitate at the site of membrane lesions. However, little is known about the origins of lipids and proteins for resealing and repair of the plasma membrane.

Live two-way video versus face-to-face treatment for depression, anxiety, and obsessive-compulsive disorder: A 24-week randomized controlled trial.

Aim: Live two-way video, easily accessible from home via smartphones and other devices, is becoming a new way of providing psychiatric treatment. However, lack of evidence for real-world clinical setting effectiveness hampers its approval by medical insurance in some countries. Here, we conducted the first large-scale pragmatic, randomized controlled trial to determine the effectiveness of long-term treatment for multiple psychiatric disorders via two-way video using smartphones and other devices, which are currently the primary means of telecommunication.

Case 2 involved a 78-year-old woman who was admitted to our hospital because of muscle weakness, bilateral shoulder pain, diffuse subcutaneous edema, and dysphagia that had gradually worsened during the past 5 months. Both patients showed severe diffuse subcutaneous edema and dysphagia and underwent enteral tube feeding.

transgenic line and single-cell transcriptomics reveal the origin of zebrafish intraspinal serotonergic neurons.

Sox transcription factors are crucial for vertebrate nervous system development. In zebrafish embryo, genes are expressed in neural progenitor cells and neurons of ventral spinal cord. Our recent study revealed that the loss of and function results in a significant decline of V2 subtype neurons (V2s).

Smuggling on the Nanoscale-Fusogenic Liposomes Enable Efficient RNA-Transfer with Negligible Immune Response In Vitro and In Vivo.

The efficient and biocompatible transfer of nucleic acids into mammalian cells for research applications or medical purposes is a long-standing, challenging task. Viral transduction is the most efficient transfer system, but often entails high safety levels for research and potential health impairments for patients in medical applications. Lipo- or polyplexes are commonly used transfer systems but result in comparably low transfer efficiencies.

Fat Grafts Show Higher Hypoxia, Angiogenesis, Adipocyte Proliferation, and Macrophage Infiltration than Flaps in a Pilot Mouse Study.

Background: Over 137,000 breast reconstructions are performed annually by American Society of Plastic Surgeons (ASPS) members. Vascularized flaps and avascular lipofilling each account for over 33,000 autologous reconstructions. Although clinical and experimental observations suggest biologic differences with diverging effects on locoregional tumor control, comparative animal models are lacking.

Serial Magnetic Resonance Imaging and Magnetic Resonance Angiographic Findings of Reversible Cerebral Vasoconstriction Syndrome Associated with Postpartum.

We report 2 cases of reversible cerebral vasoconstriction syndrome (RCVS) associated with postpartum. In case 1, a 26-year-old woman developed sudden-onset headache, nausea, and vomiting 1 h after an uncomplicated vaginal delivery. In case 2, a 27-year-old woman developed generalized seizures 9 days after an uncomplicated vaginal delivery.

Phenotypic Discovery of Triazolo[1,5-]quinazolines as a First-In-Class Bone Morphogenetic Protein Amplifier Chemotype.

Phenotypic drug discovery (PDD) continues to fuel the research and development pipelines with first-in-class therapeutic modalities, but success rates critically depend on the quality of the underlying model system. Here, we employed a stem cell-based approach for the target-agnostic, yet pathway-centric discovery of small-molecule cytokine signaling activators to act as morphogens during development and regeneration. Unbiased screening identified triazolo[1,5-]quinazolines as a new-in-class in vitro and in vivo active amplifier of the bone morphogenetic protein (BMP) pathway.

Highly Fluorinated Peptide Probes with Enhanced In Vivo Stability for F-MRI.

A labeling strategy for in vivo F-MRI (magnetic resonance imaging) based on highly fluorinated, short hydrophilic peptide probes, is developed. As dual-purpose probes, they are functionalized further by a fluorophore and an alkyne moiety for bioconjugation. High fluorination is achieved by three perfluoro-tert-butyl groups, introduced into asparagine analogues by chemically stable amide bond linkages.

Enhanced surveillance for adverse events following immunization during the 2019 typhoid conjugate vaccine campaign in Harare, Zimbabwe.

Background: During February 25-March 4, 2019, Zimbabwe's Ministry of Health and Child Care conducted an emergency campaign using 342,000 doses of typhoid conjugate vaccine (TCV) targeting individuals 6 months-15 years of age in eight high-risk suburbs of Harare and up to 45 years of age in one suburb of Harare. The campaign represented the first use of TCV in Africa outside of clinical trials.

Methods: Three methods were used to capture adverse events during the campaign and for 42 days following the last dose administered: (1) active surveillance in two Harare hospitals, (2) national passive surveillance, and (3) a post-campaign coverage survey.

Loss of the Bardet-Biedl protein Bbs1 alters photoreceptor outer segment protein and lipid composition.

Primary cilia are key sensory organelles whose dysfunction leads to ciliopathy disorders such as Bardet-Biedl syndrome (BBS). Retinal degeneration is common in ciliopathies, since the outer segments (OSs) of photoreceptors are highly specialized primary cilia. BBS1, encoded by the most commonly mutated BBS-associated gene, is part of the BBSome protein complex.

Two plus one is almost three: a fast approximation for multi-view deconvolution.

Multi-view deconvolution is a powerful image-processing tool for light sheet fluorescence microscopy, providing isotropic resolution and enhancing the image content. However, performing these calculations on large datasets is computationally demanding and time-consuming even on high-end workstations. Especially in long-time measurements on developing animals, huge amounts of image data are acquired.

Methylmercury-induced hair cell loss requires hydrogen peroxide production and leukocytes in zebrafish embryos.

Hearing impairment and deafness is frequently observed as one of the neurological signs in patients with Minamata disease caused by methylmercury (MeHg) poisoning. Loss of hair cells in humans and animals is a consequence of MeHg poisoning. However, it is still not clear how MeHg causes hearing deficits.

Neuron-Radial Glial Cell Communication via BMP/Id1 Signaling Is Key to Long-Term Maintenance of the Regenerative Capacity of the Adult Zebrafish Telencephalon.

The central nervous system of adult zebrafish displays an extraordinary neurogenic and regenerative capacity. In the zebrafish adult brain, this regenerative capacity relies on neural stem cells (NSCs) and the careful management of the NSC pool. However, the mechanisms controlling NSC pool maintenance are not yet fully understood.

Anxiety related to infection, stress and stigma caused by the forced changes in daily life have reportedly increased the incidence and symptoms of depression, anxiety disorder and obsessive-compulsive disorder. Under such circumstances, telepsychiatry is gaining importance and attracting a great deal of attention.

Behavior of the Antibacterial Peptide Cyclo[RRRWFW], Explored Using a 3-Hydroxychromone-Derived Fluorescent Amino Acid.

Labeling biomolecules with fluorescent labels is an established tool for structural, biochemical, and biophysical studies; however, it remains underused for small peptides. In this work, an amino acid bearing a 3-hydroxychromone fluorophore, 2-amino-3-(2-(furan-2-yl)-3-hydroxy-4-oxo-4H-chromen-6-yl)propanoic acid (FHC), was incorporated in a known hexameric antimicrobial peptide, cyclo[RRRWFW] (cWFW), in place of aromatic residues. Circular dichroism spectropolarimetry and antibacterial activity measurements demonstrated that the FHC residue perturbs the peptide structure depending on labeling position but does not modify the activity of cWFW significantly.

Isoniazid preventive therapy use among adult people living with HIV in Zimbabwe.

We assessed the prevalence of isoniazid preventive therapy (IPT) uptake and explored factors associated with IPT non-uptake among people living with HIV (PLHIV) using nationally representative data from the Zimbabwe Population-based HIV Impact Assessment (ZIMPHIA) 2015-2016. This was a cross-sectional study of 3418 PLHIV ZIMPHIA participants eligible for IPT, aged ≥15 years and in HIV care. Logistic regression modeling was performed to assess factors associated with self-reported IPT uptake.
