In 1992, a patient, born July 10, 1910, aged 82, with major osteoporosis [1-3], was operated on her left hip. The surgeon performs a biomaterial transplant using natural coral [4]. Follow-up is two years. She died in 1994 of acute respiratory failure. Three bone graft osteodensitometry [5] shows a regular increase in mineralization; however, on the opposite side, bone mineralization decreases. The anatomical part is examined using x-rays, scanners, photographs, histology [6]. The article reports the findings of this study. It is noted a partial resorption of the biomaterial essentially at the periphery of the graft as well as the different local connections of the preexisting bone with the newly formed bone from the grafted area. The severity of fractures of the femoral neck is no longer to be demonstrated [7]. Multiple therapeutic trials have demonstrated their effectiveness [8,9]. Twenty two patients were transplanted. There was no failure. All died without fracturing their grafted hips. 

It was pyrite from Congo which conducts electricity but cannot store it as the existing event of catalytic nanomotors. Herewith provided discussion and description from nanodiamond contained in meteorite to alkylation reaction any catalytic nanomotors proposed to enhance the built-in DNA-wave biocomputer.We found chondrite meteorites in primitive types of space rock.

Concussion diagnosis is a clinical categorization that often rests primarily on symptom reporting. However, diagnostic criteria require certain signs and symptoms to be either ruled in or ruled out. 

Direct rigid pharyngoscopy, laryngoscopy and oesophagoscopy are very common procedures in the Otolaryngology-Head & Neck department, both for diagnostic and therapeutic purposes. The phayngoscopes, laryngoscopes and oesophagoscopes are solid straight metal instruments to facilitate examination and passage of instruments through them. The process of pharyngo-laryngo-oesophagoscopy invariably involves some contact with the upper dentition resulting in some pressure over the teeth and jaw when suspension laryngoscopy is carried out. 

Hypoxis hemerocallidea Lam is one of the 43 Hypoxis species in South Africa, marketed extensively as over the counter herbal product for the management of several diseases. The plant commercial products link efficacy to hypoxoside 4, its aglycone (rooperol), or β-sitosterol. This study investigated antibacterial and anti-oxidant activities of four other molecules and two extracts from the Hypoxis plant. Visual antioxidant limit of detection and free radical scavenging activities of test samples were determined using 20 mM hydrogen peroxide, 0.4 mM DPPH or ferric reducing antioxidant power assay. Quantitative free radical was determine by spectrophotometric method while antibacterial activity was evaluated using MICs against uropathogens: S. aureus (ATCC25923), S. marcescens (ATCC 14041), P. aeruginosa (ATCC 9721), P. mirabilis (ATCC 33583) and E. coli (ATCC 10536). Anti-oxidant activities visual limit of detection of 0.06 mg/mL and percentage free radical scavenging activity (IC50 = 0.048 - 0.032 mg/ml) for pure compounds 1 - 4 and (IC50 = 0.037 - 0.039 mg/ml) for extracts were obtained. The reducing power IC50 ranged between 0.15 - 0.23 mg/ml for extracts and 0.11-0.35 mg/ml for standards. Antibacterial potentials show a noteworthy to moderate MIC values of 0.20 - 1.56 mg/ml against S. aureus (ATCC 25923), S. marcescens (ATCC 14041), P. aeruginosa (ATCC 9721), P. mirabilis (ATCC 33583) and E. coli (ATCC 10536). Galpinoside 5, hemerocalloside 3 and curculigoside C 2 are the other active compounds in Hypoxis plant.

Background/Aim: In spite of global initiatives to provide sight for all by the year 2020, many middle-aged to elderly people in the Niger Delta still have significant visual impairment due to uncorrected refractive errors. The aim of this study is to assess the types of refractive anomalies that occur among presbyopic patients in Port Harcourt and determine the demographic pattern of these anomalies based on age and gender characteristics. Methodology: This is a hospital-based descriptive cross-sectional study in which sixty consecutive adult patients for refraction were seen. Every adult patient that came to get glasses during the study period was included in the study except where ocular or systemic contraindications were present. In addition to visual acuity, all patients had a detailed ocular examination and then refraction. The collected data was subsequently analysed using SPSS version 20. Results: The mean age of the patients was 54.4 ± 9.4 years with a range of 35 to 80 years. A total of 60 patients were seen, comprising 30 males and 30 females. The commonest refractive error was presbyopia with hyperopic astigmatism and this accounted for 80% of all cases. Hyperopic presbyopia and presbyopia alone were the least common. Conclusion: There is a high level of cylindrical and spherical errors in Port Harcourt. The full optical correction should always be prescribed to presbyopic patients to fully correct the associated visual impairment and improve the patients’ well-being.

Urinary Tract Infection (UTI) is very common in our community most specifically in married females with numerous antecedent risk factors. The aim of the study was to find out about the current risk factors and clinical profile of urinary tract infections in patients admitted to the cardiology ward of Afghan Momand Medical Complex for various purposes.It was a cross-sectional descriptive hospital-based study including both male and female patients visiting the Afghan Momand Medical Complex from January 2022 to June 2022. Of all 960 patients, 202 (21%) patients had urinary tract infections with gender distribution as 69 (34.2%) males and 133 (65.8%) females. In fact, 33 (16.3%) patients with urinary tract infections were single while the rest 169 (83.7%) patients were married. In addition, regarding clinical profile, the following clinic was respectively more prevalent: Dysuria in 120 (59.4%) patients, flank pain in 73 (36.1%) patients, urine frequency in 67 (33.1%) patients, urgency in 36 (17.8%) patients, fever in 24 (11.8%) patients, and nausea and vomiting in 19 (9.4%) patients. Moreover, the following risk factors were respectively the most common ones: Diabetes mellitus 86 (42.5%), pregnancy 30 (14.9%), stones 15 (7.4%), 10 (4.9%) devices, 10 (4.9%) prostatic hyperplasia, and 4 (2%) anatomical anomalies.Urinary tract infection is a common disease in the admitted patients in Afghan Momand Medical Complex specifically being more common in females and early 20s of the age. In fact, diabetes, pregnancy, and kidney stones were the leading associated factors with UTI. Moreover, dysuria, bladder emptying irritative symptoms, and abdominal pain were the most prevalent clinical profile of the patients. Special attention should be paid to infectious diseases in cardiac patients since infection itself is a stress and a threat to such patients and authorities should design special measures to prevent UTI in the general population to avoid a sum of burden on the health system.

Sleep disorders in human are common and detrimental to general health of all age groups. While the neurobiological mechanisms of sleep disorders are not yet fully understood, recent advances in research on the sleep-wake regulation mechanism, genetic and epigenetic factors, cognitive, emotional and physiological changes related to sleep have shed light on the mechanistic basis of sleep disorders. Over the past two decades, studies in Drosophila have yielded new insights into basic questions regarding sleep function and regulation. More recently, powerful genetic approaches in the fly have been applied toward studying primary human sleep disorders and other disorders associated with dysregulated sleep. In this review, we discussed recent advances in neurobiology of sleep-wave cycle and common sleep disorders. Understanding these mechanisms are important in the diagnosis, treatment and prevention of these common disorders.

Known since antiquity, migraine is a complex primary disorder, an episodic painful Autonomic Nervous System (ANS) storm, generally following the stress/post-stress phase. Despite exhaustive study of neuropeptides, neurochemicals, molecules, neurogenetics, neuroimaging along with animal and human experiments over the last 50 years, the scientific basis of migraine remains unknown. Straddling eight decades from Cortical Spreading Depression (CSD) to Calcitonin-Gene Related Peptide (CGRP) and its antagonists, exponentially increasing data have failed to create a gestalt synthesis. This article lays cohesive and robust fundamental principles for the comprehension and management of migraine. The continuum between migraine and non-congestive Primary Open-Angle Glaucoma (POAG), Normal Tension Glaucoma (NTG), or Low-Tension Glaucoma (LTG) is advancing. The case of sustained remission of migraine attacks (> 75%) over 3 years - 5 years with ocular hypotensive topical Bimatoprost Ophthalmic Solution (BOS) 0.3% in an N-of-1 trial in 3 patients with refractory migraine is presented. A cause-effect-adaptive process underlies the ANS-stress/post-stress-linked biology of migraine. Vasopressin-serotonin-norepinephrine ‘homeostatic-adaptive system’ Lowers Intraocular Pressure (IOP), while enhancing anti-stress, antinociception, vasomotor, and behaviour control functions, thereby selectively decreasing algogenic neural traffic in the ophthalmic division of trigeminal nerve (V1), and, raising the threshold to develop migraine. Striking migraine headache-aborting feature of vomiting is also likely linked to a several hundred-fold increase in arginine-vasopressin secretion. Eye-cover tests and self-ocular digital displacement are essential to studying the visual aura. Real-time physical displacement of Scintillating Scotoma (SS) and floating ‘stars’ is reported. The basis of spontaneous onset and offset, self-limited duration of migraine attacks, as well as female preponderance, and age/menopause decline in prevalence, are elucidated. Intraocular implants with long-term ocular hypotensive effects, including bimatoprost, are the future of migraine management. Controlled trials are required to establish the migraine-preventive effect of topical bimatoprost, a revolutionary advance in neuroscience.

The pandemic of COVID-19 has adversely affected the world in many aspects. The health and economic sectors suffer most of the repercussions of this disease. The search for a cure for this rapidly spreading virus which is causing massive life losses worldwide requires clear understanding of the immunopathogenesis of this virus so as to develop pinpointed targeted therapies rather than relying mainly on supportive care measures and drug repurposing to fight this life-threatening virus infection. Neutrophils, neutrophil extracellular traps (NETs), and NETosis are not well studied not only in COVID-19, but also in coroviruses in general. The review will shed lights on the functions of neutrophils, NETs, and NETosis in various infectious complications as well as in sepsis and acute lung conditions in an attempt to understand their actual roles and in order to help in designing targeted therapies in the near future.
