New insight into the kinetic study on the different loadings of the CuO/CNT catalyst and its optimization for -chloroaniline photodegradation.

The effect of the copper (Cu) content on Cu oxide loaded onto a carbon nanotube (CuO/CNT) catalyst on the mechanistic, kinetic, and photonic efficiency of the photodegradation of -chloroaniline (PCA) under visible (Vis) and ultraviolet (UV) light irradiation has been explored. For low-loading (1-5 wt%) CuO/CNTs, photodegradation performed better under UV (>84%) rather than the Vis system; this may be due to the presence of abundant defect sites on both CuO and CNTs, which allowed the multielectron reduction of oxygen at their impurity levels to generate more hydrogen peroxide and subsequent ·OH radicals. The active species under UV were in the following order: h ≫ e > ·OH, while it was for the Vis system with a well-balanced 50 wt% CuO/CNT catalyst that exhibited a similar performance.

Interaction Insight of Pullulan-Mediated Gamma-Irradiated Silver Nanoparticle Synthesis and Its Antibacterial Activity.

The production of pure silver nanoparticles (Ag-NPs) with unique properties remains a challenge even today. In the present study, the synthesis of silver nanoparticles (Ag-NPs) from natural pullulan (PL) was carried out using a radiation-induced method. It is known that pullulan is regarded as a microbial polysaccharide, which renders it suitable to act as a reducing and stabilizing agent during the production of Ag-NPs.

Supporting Kenyan women with advanced breast cancer through a network and assessing their needs and quality of life.

Introduction: Metastatic breast cancer (MBC) patients have several unmet needs. The needs and quality of life of MBC women living in sub-Saharan Africa (SSA) are understudied. Facilitating the interaction of various caregivers is beneficial in addressing the needs.

Nanometal Dust Explosion in Confined Vessel: Combustion and Kinetic Analysis.

Extensive application of metal powder, particularly in nanosize could potentially lead to catastrophic dust explosion, due to their pyrophoric behavior, ignition sensitivity, and explosivity. To assess the appropriate measures preventing accidental metal dust explosions, it is vital to understand the physicochemical properties of the metal dust and their kinetic mechanism. In this work, explosion severity of aluminum and silver powder, which can be encountered in a passivated emitter and rear contact (PERC) solar cell, was explored in a 0.

A Case of Multiple Myeloma Presenting with Gastrointestinal Bleeding and Evans Syndrome.

Autoimmune events are rare in multiple myeloma (MM). Herein, we report a rare case of a patient presenting with recurrent gastrointestinal (GI) bleeding of unknown origin, also having pancytopenia eventually diagnosed as MM with Evans syndrome. This is an uncommon disorder presenting as autoimmune hemolytic anemia (AIHA) with immune thrombocytopenia purpura (ITP).

Sweet hydrothorax: a common presentation of a rare condition.

Sweet hydrothorax is a known, yet rare, complication of peritoneal dialysis. It can be life-threatening. This case is about a 70-year-old lady who presented with acute respiratory failure due to massive right-sided hydrothorax that developed insidiously over 3 months of starting peritoneal dialysis.

Breast Camps for Awareness and Early Diagnosis of Breast Cancer in Countries With Limited Resources: A Multidisciplinary Model From Kenya.

Background: Breast cancer is the most common cancer of women in Kenya. There are no national breast cancer early diagnosis programs in Kenya.

Objective: The objective was to conduct a pilot breast cancer awareness and diagnosis program at three different types of facilities in Kenya.

Minimal change disease associated with MALT lymphoma.

Low-grade Extranodal Marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, a subtype of non-Hodgkin's Lymphoma, involving the kidney is a rare clinical entity. Association of Minimal change disease nephrotic range proteinuria with Hodgkin's lymphoma is well described, however is extremely uncommon with non-Hodgkin's lymphoma. We describe a patient who presented with nephrotic syndrome and a kidney biopsy revealed marginal zone lymphoma and diffuse epithelial foot process effacement.

Cavitary lung lesions in systemic lupus: an unusual presentation.

Lupus is a multisystem disease with varied clinical manifestations. Cavitary lung lesions in lupus could be secondary to infections, embolism, or underlying vasculitis. We report a man who presented with lung cavitations and was diagnosed as lupus, secondary antiphospholipid syndrome, and plasma cell dyscrasia.

Metal fume-induced diffuse alveolar damage.

Metal fume fever is a well-defined clinical entity characterized by a self-limited influenza-like illness. Severe and protracted illness related to metal fume exposure is rare. We describe 2 related cases of serious metal fume fever in a 29- and a 51-year-old male precipitated by the use of an acetylene torch to dismantle galvanized steel in a poorly ventilated area.

Guillain-Barré syndrome as a paraneoplastic manifestation of small-cell carcinoma of lung.

Guillain-Barré syndrome (GBS) encompasses the variants of acute immune-mediated polyneuropathies usually preceded by an infection. A few case reports have associated GBS to neoplastic diseases. It remains unclear whether these are merely coincidental or represent paraneoplastic phenomena.

An endobronchial lipoma mimicking asthma and malignancy.

Endobronchial lipomas are rare benign tumours of the lung. Bronchial occlusion may lead to a misdiagnosis of asthma or malignancy. We describe a 52-year-old man treated for asthma for several years, who presented with non-resolving right upper lobe pneumonia.

Disseminated histoplasmosis diagnosed on bone marrow aspirate cytology: report of four cases.

Histoplasmosis, caused by two varieties of dimorphic fungi, Histoplasma capsulatum variant capsulatum and Histoplasma capsulatum variant duboisii is a systemic fungal infection. It has a worldwide distribution and is shown to be more prevalent in North America and Central America. Both variants occur in Africa.

Microscopic polyangiitis triggered by recurrent methicillin-resistant Staphylococcus aureus bacteremia.

Most of the purported links between microbial agents and primary small-vessel anti-neutrophilic antibody-positive (ANCA) vasculitides remain speculative. There is strong circumstantial evidence for the role of Staphylococcus aureus in the development of Wegener's granulomatosis, but its role in other ANCA-positive vasculitis syndromes is less clear. We describe a patient who developed a non-granulomatous, necrotizing small-vessel vasculitis with a positive anti-neutrophil cytoplasmic antibody of a perinuclear type (p-ANCA), along with anti-myeloperoxidase antibodies after recurrent episodes of methicillin-resistant Staphylococcus aureus bacteremia.

An incidental right atrial mass: cavernous hemangioma.

Cardiac hemangiomas are rare benign tumors of the heart typically diagnosed incidentally. We report a case of a 70-year-old man with a right atrial cavernous hemangioma and a concomitant pulmonary embolism. The possible association, clinical features, operative procedure, and pathologic findings are described.

Hyperkalemia and cocaine induced dynamic Brugada-type electrocardiogram.

Brugada syndrome is a well-defined clinical entity with the typical electrocardiographic changes in the right precordial leads (V1 and V2), attributed to mutation in SCN5A gene. Brugada-like electrocardiographic pattern can be replicated by sodium channel-blocking drugs and electrolyte abnormalities. We describe a 46-year-old individual, who presented with hyperkalemia secondary to muscle damage and renal insufficiency, after abusing cocaine.

Simultaneous ST-segment elevation in inferior and precordial leads following ingestion of a lethal dose of desipramine: a novel Brugada-like EKG pattern.

The typical Brugada electrocardiographic (EKG) pattern includes ST-segment elevation in the right precordial leads (V1-V3) associated with right bundle branch block (rSR') like morphology. Recently, a Brugada-like EKG pattern with ST-segment elevation in inferior leads called the "Brugada variant" has been reported. We report a case of simultaneous typical and variant Brugada EKG patterns with ST-segment elevation in the inferior as well as the precordial leads following ingestion of a lethal dose of desipramine.
