The present work aims to study a convenient and environmentally friendly method for the green synth of silver nanoparticles (AgNPs based on lemon juice extract. The biomolecules contained in lemon extract act as self- reducing and stabilizing agents. The optimal solution for the synthesis of AgNPs was determined by varying silver nitrate concentrations. A surface plasmon resonance system identified the synthesized silver nanoparticles by their color change from colorless to dark brown. Silver nanoparticles synthesized were characterized by Uv-visible (UV-Vis) spectroscopy, high-resolution transmission electron microscopy (HR-TEM), and FTIR spectroscopy. As a result of UV-visible spectroscopy, surface plasmon resonance (SPR) can be determine

Primary coenzyme Q10 deficiency-4 (CoQ10D4) is an autosomal recessive disorder characterized by childhood-onset of cerebellar ataxia and exercise intolerance. Molecular pathology responsible for clinical findings is mitochondrial respiratory chain dysfunction. The main clinical manifestation involves early-onset exercise intolerance, progressive cerebellar ataxia and movement disorders. Some affected individuals develop seizures and have mild mental impairment, indicating variable severity.

A new method for repacking optical metamaterials formed from fiber or spherical elements of various diameters is proposed for ultraviolet C (UVC) decontamination of infected liquids that flow between these elements. It is proposed the method of repacking of metamaterial formed from closed packing big fibers/spheres with other subsystems of thin fibers/ bubbles replaced in the free space between the first packing fibers/spheres.

The case was a 7-year-old girl who had complained of bilateral blurry vision for 1 week. Five weeks earlier, she suffered from a flu-like episode with fever, sore throat, and skin rash, and received an irregular dose of oral amoxicillin for 4 days after a diagnosis of scarlet fever. Our clinical examination revealed bilateral panuveitis with frosted-branch angiitis.

The endeavor of this research accounts for a superficial green route scheme by using an extract of leaves of Smilax aspera as a stabilizing and capping agent. Zinc Oxide nanoparticles (ZnO-NPs) were examined through UV-visible Spectrophotometer, X-Ray Diffraction (XRD), EDX (Energy Dispersive X-rays spectroscopy), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM). The NPs demonstrates potential photo catalytic activity for the degradation of Methyl Orange (MO) and Methylene Blue (MB) dyes upon exposure to sunlight.

Inflammatory bowel disease (IBD) is a common yet distressing condition afflicting tissues of the gastrointestinal (GI) tract in companion animals; symptoms include vomiting, diarrhoea, loss of appetite and weight loss. Pathogenesis of IBD may link to both diet and parasitic or bacterial infections of the gut. Although current treatments may provide some relief to the animal, unfortunately recurrent flaring of symptoms is not uncommon. Therapeutic interventions available to the veterinarian include those that focus on treating any underlying infection and or a change in diet, both employed with the aim of reducing inflammation.

Gigantomastia is a rare condition which remains poorly understood. There is no universally accepted definition, however breast weight exceeding 3% of total body weight has been proposed. Juvenile gigantomastia, a subtype, involves sudden onset, excessive growth of breast tissue in relation to puberty and can occur before or after the onset of menstruation. This paper reports on the first known case of juvenile gigantomastia seen in the United Kingdom. A 16-year old female presented with a 12-month history of rapid breast growth. She had no other medical problems and no relevant family history. Examination revealed bilaterally enlarged breasts extending to the level of the anterior superior iliac spine, with enlarged superficial veins, ill-defined areola and areas of skin ulceration. A range of hormone and autoimmune tests were performed with all results found to be normal. After MDT discussion, the treatment of choice was reduction mammoplasty with an inferior pedicle technique and free nipple grafting if necessary. The total volume of tissue removed weighed 10.9 kg; 6.6 kg from the right breast, 4.3 kg from the left breast. Initial post-operative results demonstrate a highly satisfactory reduction with minimal scarring and no further growth of breast tissue. Histology showed a benign pattern secondary to extensive proliferation of glandular and stromal tissue. The tissue tested positive for both oestrogen and progesterone receptors and so the decision was made to treat the patient with tamoxifen until the age of 21 years in order to prevent recurrence. To our knowledge, this is the first reported case of juvenile gigantomastia in the UK.

Paracoccidioidomycosis (PCM) is a systemic disease caused by thermo- dimorphic fungi of Paracoccidioides genus that is endemic in several Latin American countries. The treatment for this disease can be performed with different drugs. In general, it is a long duration treatment that aims the control of the clinical manifestations. Even after treatment, the patient usually shows relapse and incapacitating sequelae, such as fibrosis and pulmonary emphysema.

Juvenile idiopathic epilepsy (JIE) is a self-limiting neurological disorder with a suspected genetic predisposition affecting young Arabian foals of the Egyptian lineage. The condition is characterized by tonic-clonic seizures with intermittent post-ictal blindness, in which most incidents are sporadic and unrecognized. This study aimed to identify genetic components shared across a local cohort of Arabian foals diagnosed with JIE via a combined whole genome and targeted resequencing approach: Initial whole genome comparisons between a small cohort of nine diagnosed foals (cases) and 27 controls from other horse breeds identified variants uniquely shared amongst the case cohort.

Prenatal development consists of three stages in dogs. These stages are called preimplantation, embryonic and fetal period respectively. Embryonic or fetal losses may occur as a result of any causes that damage embryo or fetus during prenatal development period. These losses are called resorption, abortion, mummification and maceration according to the stage of pregnancy. Fetal maceration is often observed in cattle, but also can occur in other domestic animals. The incidence is quite low in bitches. The materials of this case were two bitches in different breeds that are Pointer and Golden retriever. They were brought to Clinics of Obstetrics and Gynecology by their owners with the complaints of growth in their abdomen, increase in weight and decrease in movements at different times. Firstly, detailed anamnesis was taken from their owners. As the mating status of both bitches is unknown, the probabilities of pregnancy and pregnancy pathologies have been neglected in the clinics previously referred to with the same complaints and both bitches were diagnosed with obesity by considering breed predisposition. In this context, it was learned that there was no treatment except for the suggestion of on low energy content foods and exercises however no healthy improvements were observed in both bitches. Gynecological, ultrasonography and radiographic examinations, whole blood and serum biochemistry analysis were performed on both bitches after anamnesis was taken. When the findings of the analysis and examination were evaluated, it was concluded that the fetuses were autolyzed in the uterus without being aborted. It was concluded to perform ovariohysterectomy operation on both dogs for treatment. When the removed uterus tissues were examined, it was seen that both bitches had fetal maceration.

Benign paroxysmal positional vertigo (BPPV) is a common peripheral vestibular disease; however intracranial lesions can mimic it. Intractable, not self-limiting paroxysmal positional vertigo sustained by intracranial tumors is called malignant paroxysmal positional vertigo (MPPV) while, when radiological imaging shows vascular cerebellar vermis lesions and there are atypical findings on the Dix-Hallpike maneuver, we speak about pseudo-benign paroxysmal type (pseudo-BPPV).

Human epidermal growth factor receptor 2 (HER2) is responsible for the pathogenesis and poor outcomes of several types of cancers, including advanced gastric and gastroesophageal junction cancer. Molecular-targeted drugs on the other hand, such as trastuzumab, prolong overall survival and progression-free survival in HER2-positive gastric cancer. The purpose of the case report is to evaluate the impact of delivering trastuzumab in advanced gastric cancer with concomitant HER2 mutation and amplification.
