Investigations include histology with amyloid stains like Congo red, immunohistochemistry to identify the amyloid precursor protein, and electron microscopy for definitive confirmation.
Skin infections
The document discusses skin infections and dermatosis. It defines dermatosis as diseases of the integumentary system, including skin, nails, and hair. It describes four main types of skin infections - bacterial, viral, fungal, and parasitic - listing examples of each type and their symptoms. The document also covers causes, diagnosis, treatment and prevention of skin infections. It then discusses various skin conditions that are considered dermatosis, providing examples of common and less common forms.
Seborrheic dermatitis
Seborrheic dermatitis (SD) is a common chronic skin condition characterized by redness and scaling in areas with many sebaceous glands like the face, scalp, and skin folds. It causes mild flaking of the scalp known as dandruff. Lesions can be itchy or painful and look deep red or purple with pimple-like bumps or blisters. Treatment involves topical anti-fungal creams, steroid creams, or oral anti-fungal medication for deep infections.
Tinea versicolor
Tinea versicolor is a common skin infection caused by the Malassezia fungus. It causes patches of discolored skin but is not harmful or contagious. While it may cause emotional distress, the fungus usually lives harmlessly on the skin. Tinea versicolor is more common in teenagers due to hormones and occurs in people of all ages. Factors like weak immune systems, hormones, sweat, and heat can cause the fungus to overgrow and discolor patches of skin.
Ear infection
This document discusses different types of ear infections:
- Otitis externa is inflammation of the external ear canal and can be caused by bacteria, fungi, or other factors. Acute cases involve pain while chronic cases involve pruritus. Treatment involves cleaning and antibiotics.

- Otitis media with effusion involves fluid in the middle ear without infection. It often follows acute otitis media and can cause temporary hearing loss. Most cases
Paragonimiasis (lung fluke disease)
Paragonimiasis is caused by lung fluke parasites of the genus Paragonimus. People become infected by eating raw or undercooked freshwater crabs or crayfish containing infective parasite cysts. The parasites migrate through the intestines and lungs, causing inflammation and symptoms like coughing up blood. Diagnosis involves finding parasite eggs in sputum or stool samples under the microscope or using serology tests. Chest x-rays may also show signs of lung damage from migrating parasites. There is no vaccine and treatment involves antiparasitic medications.
Congenital disorders of nose
In children with congenital nasal disorders, supportive care of the
airway is given until the diagnosis is established. Diagnosis is
made through a combination of ?exible scoping and imaging
studies, primarily CT scan. In the case of surgically correctable
congenital problems such as choanal atresia, surgery is performed
once the child is deemed healthy and free of life-threatening
problems such as congenital heart disease.

The clinical presentation includes patchy erythema becoming universal over 24-48 hours accompanied by malaise, shivering and pyrexia, followed by scaling after 2-6 days. Erythroderma can be caused by conditions like eczema, psoriasis, malignancy, and drug reactions. Complications can include edema, lymphadenopathy, cardiac failure, metabolic disturbance, hypothermia, and cutaneous or respiratory infection. Management involves close inpatient monitoring and initially topical st
Ascariasis
This document describes ascariasis, caused by the roundworm Ascaris lumbricoides. It is most common in children in tropical areas with poor sanitation. The worms live in the small intestine and the female can lay up to 200,000 eggs daily that are passed in feces. When eggs are ingested, they hatch in the intestines releasing larvae that migrate through organs before maturing in the lungs and being swallowed to the intestines. Heavy infections can cause malnutrition, obstruction, and other complications. Diagnosis involves finding eggs in stool or worms. Treatment includes mebendazole or pyrantel pamoate. Prevention relies on proper sanitation and hygiene.

Deuteromycota refers to fungi that reproduce asexually and whose sexual reproduction cycle is unknown. They are characterized by septate mycelium and reproduce through conidia. There are four orders within Deuteromycota distinguished by where conidia and conidiophores are produced. Some Deuteromycota have sterile mycelium or sclerotia and some undergo a parasexual cycle involving plasmogamy and haploidization but not true meiosis.
Dermatophytes
Dermatophytes are fungi that infect keratinized tissues like skin, hair, and nails. There are three genera of dermatophytes: Microsporum, Trichophyton, and Epidermophyton. They produce enzymes that allow them to invade keratinized tissues. Dermatophyte infections can occur on the scalp (tinea capitis), beard (tinea barbae), body (tinea corporis), groin (tinea cruris), hands (tinea manum), and feet/nails (tinea pedis/unguium). Diagnosis involves microscopic examination of skin or nail samples in potassium hydroxide (KOH), culture, and sometimes PCR.

Fluidelectrobalance 100225143758-phpapp01
Fluids and electrolytes are essential for normal body function. Electrolytes like sodium, potassium, chloride, and bicarbonate help regulate fluid balance and pH. There are three main fluid compartments - intracellular, interstitial, and intravascular. Fluids can shift between compartments through processes like diffusion, osmosis, and active transport. Imbalances can cause edema. Monitoring for edema, vital signs, and lab values is important to assess fluid status and guide treatment like fluid resuscitation.
(Hypo vs hyperkaemia)
This document discusses compositional imbalances of potassium, specifically hypokalemia and hyperkalemia. It notes that potassium regulation depends on aldosterone, catecholamines, insulin, and acid-base balance. Hypokalemia is defined as a serum potassium concentration below 3.5 mEq/L and can be caused by decreased oral intake, gastrointestinal loss through vomiting or diarrhea, or renal loss due to diuretic use, renal disease, or other conditions. Signs and symptoms of hypokalemia include fatigue, muscle weakness, cardiac issues, and gastrointestinal problems.
Hypovolemia
This document discusses isotonic fluid imbalance, also known as hypovolemia. Hypovolemia occurs when water and electrolytes are lost in equal proportions, keeping sodium levels normal. It can result from extra-renal losses like vomiting, diarrhea, burns, or third spacing of fluids. It can also occur due to renal losses from conditions like renal disease or diuretic use. When fluid volume is depleted, the body activates compensatory mechanisms like increasing antidiuretic hormone and renin-angiotensin-aldosterone system to conserve water and sodium. This helps maintain blood pressure and cardiac output. Symptoms of hypovolemia include thirst, fatigue, dizziness, decreased skin turgidity,
Snr urinary systems_last_slides b
Neural and hormonal factors regulate glomerular filtration rate (GFR). Sympathetic nerves release norepinephrine which causes blood vessel constriction and decreases GFR. The hormones angiotensin II and atrial natriuretic peptide respectively decrease and increase GFR. Tubular reabsorption and secretion are also regulated. Most filtered water, sodium, and other solutes are reabsorbed, while the kidney secretes substances like hydrogen ions, potassium, and drugs. Hormones such as aldosterone and antidiuretic hormone impact reabsorption of water and sodium.

Presented at June 6-7 Texas Alliance of Groundwater Districts Business MeetingUnlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
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.
