Pyrfume: A window to the world's olfactory data.

Advances in theoretical understanding are frequently unlocked by access to large, diverse experimental datasets. Our understanding of olfactory neuroscience and psychophysics remain years behind the other senses, in part because rich datasets linking olfactory stimuli with their corresponding percepts, behaviors, and neural pathways remain scarce. Here we present a concerted effort to unlock and unify dozens of stimulus-linked olfactory datasets across species and modalities under a unified framework called Pyrfume.

Effect of Curing Light with Different Intensities on the Penetration of Silver and Fluoride Ions and Dentin Hardness in Primary Carious Molars Following Silver Diamine Fluoride Application: A Comparative Microscopic Study.

Background: A paradigm shift from surgical to medical approach for caries management has popularized silver diamine fluoride (SDF) as a preventive and interim caries arrest medicament. Few studies conducted have explored the effect of curing light on SDF's microbial property, its penetration, and effect on dentin. However, there is a research gap regarding the effect of different intensities of curing light on SDF performance.

Immunogenicity and safety of SARS-CoV-2 recombinant spike protein vaccine in South African people living with and without HIV-1 infection: A phase 2 randomised trial.

Background: Response data for COVID-19 vaccines in immunosuppressed individuals are typically limited to standard dosing in small populations. Adjusting number or interval of doses may impact immune responses based on HIV status.

Methods: This phase 2 randomised, observer-blinded, placebo-controlled South African study (2019nCoV-505/NCT05112848) enrolled medically stable people living with HIV (PLWH) and HIV-uninfected participants aged 18-65 years.

Statistical analysis plan for the SOLUTIONS randomised controlled trial with internal pilot: Solution Focused Brief Therapy (SFBT) in 10-17-year-olds presenting at policy custody.

Background: Within England, children and young people entering police custody are referred to Liaison and Diversion (L&D) teams. These teams liaise with healthcare and other support services aiming to divert children and young people away from the criminal justice system. Although targeted psychological interventions are not typically offered to children and young people by L&D teams, evidence suggests that Solution Focused Brief Therapy (SFBT) leads to a reduction in internalising and externalising behaviour problems.

HLA-E and NKG2A Mediate Resistance to BCG Immunotherapy in Non-Muscle-Invasive Bladder Cancer.

Bacillus Calmette-Guerin (BCG) is the primary treatment for non-muscle-invasive bladder cancer (NMIBC), known to stimulate inflammatory cytokines, notably interferon (IFN)-γ. We observed that prolonged IFN-γ exposure fosters adaptive resistance in recurrent tumors, aiding immune evasion and tumor proliferation. We identify HLA-E and NKG2A, part of a novel NK and T cell checkpoint pathway, as key mediators of resistance in BCG-unresponsive NMIBC.

The nasopharyngeal microbiome in South African children with lower respiratory tract infection: a nested case-control study of the Drakenstein Child Health Study.

Background: Lower respiratory tract infection (LRTI) is a leading cause of infant morbidity and mortality globally. LRTI may be caused by viral or bacterial infections, individually or in combination. We investigated associations between LRTI and infant nasopharyngeal (NP) viruses and bacteria in a South African birth cohort.

Validation of a novel NGS based BCR::ABL1 kinase domain mutation detection assay in Indian cohort.

The efficacy and treatment outcome of a CML patient are heavily dependent on BCR::ABL1 kinase domain (KD) mutation status. Next-generation sequencing technology is a bright alternative to the previously used sanger sequencing method due to its global presence in diagnostic setups, massive parallel sequencing ability, and far better sensitivity. In the present study, we have demonstrated a new protocol for kinase domain mutation analysis using the next-generation sequencing (NGS) method using the ion torrent sequencing platform.

A Superior Squeeze: Superior Vena Cava Syndrome Secondary to Small Cell Lung Cancer.

Superior vena cava (SVC) syndrome is an uncommon yet potentially fatal syndrome occurring after intrinsic or extrinsic compression to the SVC. While there are multiple emerging etiologies for this phenomenon, malignancy remains the most common. It is characterized by several symptoms including facial swelling, extremity swelling, shortness of breath, and headaches.

A Case of Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia in a 26-Year-Old Pregnant Woman.

Acute lymphoblastic leukemia (ALL) is an uncommon and rapidly progressing blood cancer originating in the bone marrow, characterized by the abnormal proliferation of immature lymphocytes. Although most cases of ALL are observed in children, the disease pattern shows two peaks: one in early childhood and another around the age of 50. Approximately a fifth to a third of adults diagnosed with ALL exhibit cytogenetic abnormalities involving the Philadelphia chromosome.

Using short-read 16S rRNA sequencing of multiple variable regions to generate high-quality results to a species level.

Introduction: Short-read amplicon sequencing studies have typically focused on 1-2 variable regions of the 16S rRNA gene. Species-level resolution is limited in these studies, as each variable region enables the characterisation of a different subsection of the microbiome. Although long-read sequencing techniques take advantage of all 9 variable regions by sequencing the entire 16S rRNA gene, they are substantially more expensive.
