Candidiasis
Candida albicans is a yeast that can cause infections in humans. It normally lives harmlessly in the body but can overgrow and cause disease when the environment changes. It has several forms ranging from yeast to hyphal filaments. Over 75% of women experience at least one vaginal candidiasis infection. Risk factors include antibiotics use, pregnancy, diabetes, and weakened immune system. Symptoms depend on the infected area and include rashes, vaginal discharge, and oral thrush. Diagnosis involves microscopic examination of samples. Treatment involves topical or oral antifungal drugs like fluconazole that work by disrupting the fungal cell membrane or inhibiting ergosterol production. Prevention focuses on good
Fungal & viral keratitis
1. Fungal and viral keratitis are common causes of corneal infection and blindness in tropical and developing countries. Common fungal causes are yeasts like Candida and filamentous fungi like Fusarium and Aspergillus. Predisposing factors include chronic ocular diseases, contact lens wear, and immunosuppression.
2. Clinical features of fungal keratitis include pain, discharge, infiltrates that can progress rapidly, leading to thinning and necrosis. Treatment involves topical and sometimes systemic antifungals.
3. Herpes simplex virus is a common cause of viral keratitis. It can cause epithelial keratitis with dendritic ulcers or stromal keratitis with disciform infiltr
Otomycosis
Otomycosis, or fungal ear infection, accounts for 10% of ear infections and is more common in hot, humid climates or after prolonged antibiotic use. It presents with debris-filled discharge resembling wet newspaper and sometimes visible fungal hyphae. Treatment involves removing debris from the ear and using topical antifungal drops. For resistant cases, checking for fungal infections elsewhere and potentially using systemic antifungals is recommended due to the risk of recurrence from untreated primary infections.
Enterobius vermicularis and ascaris lumbricodes
- Ascaris lumbricoides is a roundworm that inhabits the small intestine of humans.
- It produces large numbers of eggs that are passed in feces and can remain viable in soil for months.
- People become infected by ingesting these eggs. The larvae hatch and migrate through the lungs before reaching the intestine where they mature into adult worms.
- Symptoms include abdominal pain, obstruction, and malnutrition. Large numbers of worms can cause complications by blocking bile ducts or other organs. Diagnosis involves finding eggs in stool samples under microscopy.
Fungal keratitis
Fungal keratitis is a fungal infection of the cornea that is common in developing nations. It is most often caused by filamentous fungi like Aspergillus, Fusarium, and Curvularia in tropical areas, and Candida species in temperate regions. Risk factors include corneal injury, topical steroid use, diabetes, and contact lens use. Symptoms include pain, blurred vision, photophobia, and corneal ulceration. Diagnosis involves corneal scraping and culture, though PCR is more rapid. Treatment consists of topical antifungals like natamycin, amphotericin B, or voriconazole, with systemic antifungals as adjunctive therapy for severe cases

Furuncles are acute hair follicle infections while carbuncles involve adjacent follicles. Treatment options including antibiotics are outlined. Viral warts caused by HPV are also summarized, including common, plantar, plane and anogenital presentations and treatments.
Candidiasis infections
Candidiasis infections are caused by an overgrowth of the yeast Candida, which normally inhabits human mucosal surfaces. There are several types of Candidiasis depending on the infected site, including oral thrush, diaper rash, and invasive bloodstream infections. Candida albicans is the most common cause of fungal infections worldwide. It was first discovered in the 1800s and its ability to cause disease opportunistically depends on virulence factors like adhesion proteins and morphological changes between yeast and filamentous forms. Diagnosis involves microscopic examination or culturing of infected sites to identify characteristic Candida features, and treatment depends on the type and severity of infection.

Biofilms- Dr. Richa Maurya
- Bacteria frequently form biofilms, which are groups of microorganisms that attach to surfaces and produce an extracellular matrix. Over 99% of bacteria exist in biofilms.
- Biofilms provide bacteria protection from environmental threats like antibiotics. The extracellular matrix restricts antibiotic penetration and biofilms can be up to 1000 times more resistant to antibiotics than planktonic bacteria.
- Biofilm formation involves an initial attachment phase, followed by growth of colonies on the surface and eventual detachment of planktonic cells to form new biofilms elsewhere.
PARACOCCIDIOIDOMYCOSIS.pptx
Paracoccidioidomycosis is a fungal infection caused by Paracoccidioides species. It primarily involves the lungs and can disseminate to other organs. The disease ranges from asymptomatic to acute or chronic forms. Diagnosis involves microscopic examination of clinical samples to identify the characteristic yeast forms and culture growth at 37°C. Treatment requires long-term antifungal therapy for 6-12 months.

The document provides details on vaccine production methods like cell culture, egg propagation, harvesting, purification and inactivation of the virus.
Papillomatosis
Papillomatosis, also known as warts, are caused by infection with papillomavirus. The virus infects and replicates in epithelial cells, causing excessive growth and formation of warts. Warts can occur on many species of animals. Transmission occurs through direct contact with infected animals or fomites. While usually a minor problem, warts can sometimes cause significant issues. Diagnosis involves clinical appearance and histological examination. Most cases resolve spontaneously, but cryosurgery or vaccines may aid treatment. Control relies on disinfection of environments and equipment to prevent transmission.
ACTINOMYCOSIS
• Actinomyces species are classified as anaerobic, gram positive and filamentous bacteria.
• It is a chronic granulomatous suppurative and fibrosing disease caused by anaerobic or microaerophilic gram-positive nonacid fast, branched filamentous bacteria.
• Most of the species isolated from actinomycotic lesions have been identified as A. israelii, A. viscosus, A. odontolyticus, A.naeslundii or A. meyeri.
• These microorganisms have been identified in dental plaque, dental calculus, necrotic pulp, and tonsils.
• The usual pattern of this disease is one characterized chiefly by the formation of abscesses that tend to drain by the formation of sinus tracts.
• pus from the abscesses is examined on a clean glass slide, it shows the typical ‘sulfur granules’ or colonies of organisms, which appear in the suppurative material as tiny, yellow grains.
• Another infection that produces this type of sulfur granules is botryomycosis.

C2 Material Choices revision
Materials are chosen based on their properties, such as polystyrene being used for hot drink containers because it is waterproof, low density, and a poor thermal conductor. Polymers are large molecules formed from monomers joining together through polymerization. The strength and flexibility of materials depends on the forces between polymer chains and whether they are crystalline or allow for movement. Most materials are now synthetic, derived from crude oil through extraction and refining, rather than natural sources. When selecting materials, a life cycle assessment considers impacts from raw material extraction through product use and disposal.
Farmer's Bride Powerpoint
The poem describes a farmer who married a young woman who seemed afraid of intimacy and human connection. After they were married, she became withdrawn and fearful like "a little frightened fay." She eventually ran away from the farm one night. The farmer and others searched for her and found her shivering with fear, bringing her back home. Now she lives alone in the attic and keeps her distance from the farmer and other men, communicating only with animals. As winter approaches, the farmer expresses frustration at the lack of intimacy in their marriage and becomes obsessed with his wife's physical features, suggesting a growing desire or threat of violence.
Adverbs KS2
An adverb is a word that describes a verb by indicating manner, time, place, or degree. Adverbs often end in "-ly" and are commonly formed from adjectives. Examples of adverbs include "kindly", which describes how something was done, and "yesterday" or "soon", which provide temporal context about when something occurred. Adverbs add detail to writing by modifying verbs.
What is Science?
The document discusses identifying bias in scientific studies. It states that good science minimizes bias through random sampling, minimizing measurement bias, and having a large enough sample size. Bias can influence results and different scientists may find different solutions to the same problem. The scientific community engages in quality control like independent duplication of studies and peer review to eliminate bias. Results are more reliable if verified through these methods.

The videos are highlights or matches featuring prominent professional wrestlers from WWE like Roman Reigns, John Cena, Randy Orton, Daniel Bryan, CM Punk, Hulk Hogan, Batista, Brock Lesnar, The Undertaker and Triple H from different periods in their careers.
Alcohols
Alcohols contain an -OH group, meaning they contain carbon, hydrogen, and oxygen atoms. Methanol and ethanol are examples of alcohols, with molecular formulas of CH3OH and C2H5OH respectively. Alcohols burn in oxygen to produce carbon dioxide and water, and are more reactive than alkanes due to the -OH group. They can be compared to alkanes and water based on their physical properties like boiling point and ability to mix with water or react with sodium.
A3 summary higher
Organic molecules contain carbon skeletons. Alkanes contain only carbon and hydrogen atoms. Pentane has the molecular formula C5H12. Alkanes react with oxygen to produce carbon dioxide and water. Alcohols contain the hydroxyl group and ethanol has the molecular formula C2H5OH. Alcohols are used as solvents and antiseptics. Alcohols react with sodium and oxygen. Larger alcohols do not mix with water due to intermolecular forces. Carboxylic acids contain the carboxyl group and sweaty smells are caused by butanoic acid. Carboxylic acids react with sodium, potassium hydroxide, and sodium carbonate.
Alkanes
Alkanes are hydrocarbons composed only of carbon and hydrogen. Their general formula is CnH2n+2. Alkanes with fewer than 4 carbon atoms exist as gases due to weak intermolecular forces, while those with 17 or more carbons exist as solids due to stronger intermolecular forces. Alkanes are unreactive with common chemicals like acids and bases because their C-C and C-H bonds are resistant to chemicals in solution. However, alkanes can burn as fuels, with methane used for cooking/heating and gasoline containing C8H18 molecules. When burned with oxygen, alkanes produce carbon dioxide and water.

C7 revision
The hydrogen and oxygen reaction (example 1) gives out more heat energy than the hydrogen and chlorine reaction (example 2). In example 1, the energy change was -484 kJ, meaning 484 kJ of heat was given out. In example 2, the energy change was -185 kJ, meaning 185 kJ of heat was given out. Since -484 kJ is a larger negative number, the hydrogen and oxygen reaction releases more energy and is therefore more exothermic.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
