    Full Text Available The current study aimed to characterize the gross and microscopic structures of the interdigital sinus in Egyptian native breeds of sheep and goats (Baladi sheep and goats to aid in conducting farther studies on such sinus and its surgical importance. The study was carried out on the distal fore and hind limb specimens (below the fetlock joint obtained from healthy mature ten Baladi sheep and ten Baladi goats of both sexes. For sheep, thirty specimens were subjected to gross anatomical investigation and the other ten specimens were used for histological examination. While, the forty goats fore and hind feet specimens were examined grossly. The results obtained revealed the presence of a well-developed interdigital sinus in Baladi sheep, but there was no evidence for the existence of this unique structure in all examined specimens of Baladi goats. Such sinus appeared grossly as a pipe-like, composed of two parts; body (corpus and neck (column which opened in the skin of the interdigital area with an external orifice. The body consisted of three distinct parts in the forefeet and a single part in the hind feet. Histologically, the wall in body and neck regions of the interdigital sinus composed of three distinct layers; epidermis, dermis and a fibrous capsule. Many sebaceous glands, hair follicles and sweat glands in addition to the glandular apocrine gland were distributed within the dermis. The secretory adenomers of the interdigital sinus arranged in different lobules and lined with cuboidal cells with bleb-like projections. It reacted positively with Periodic Acid Schiff (PAS, Sudan black and Sudan III stains, on the other hand it negatively reacted with Alcian blue stain (AB.

  2. The impacts of grazing land management on the wind erodibility of the Mulga Lands of western Queensland, Australia (United States)

    An estimated 100 Mt of dust is eroded by wind from the Australian land surface each year. Wind erosion may be widespread across the arid and semi-arid rangelands, with impacts on soil nutrients, carbon and ecosystem services, human health, and climate. The susceptibility of landscapes to wind erosio...

  3. Estudio de erosión hídrica en varias localizaciones de la Sierra de San Miguelito, SLP, México: Evaluación de erodibilidad de los suelos y modelado del proceso


    Casabella González, Manuel Jesús


    El interés por la erosión hídrica que se muestra en este proyecto nace de la problemática existente en la actualidad en todos los ámbitos (civil, científico, político, ambiental, etc.) en torno a la conservación y protección de los principales recursos naturales esenciales, entre ellos el suelo, entendiendo al mismo como un sistema natural complejo y dinámico que cumple con determinados servicios ambientales indispensables para el sostenimiento tanto del ecosistema como de la vida h...

    Full Text Available Essential oils from herbs and roots of Conyza canadensis (horseweed, collected in Hungary, were obtained by hydrodistillation. The chemical compositions of the oils were analysed by combination of GC and GC/MS. The major constituent of the oil obtained from the aerial parts of horseweed was limonene (78%, while the main component of root oil was 2Z,8Z-matricaria ester. The antimicrobial activities of the oils were tested on Gram-positive (Enterococcus faecalis, Staphylococcus aureus, and Streptococcus pyogenes, Gram-negative (Escherichia coli, Pseudomonas aeruginosa bacteria, reference fungal strains, and fungal strains isolated from patients (Candida, Cryptococcus, Trichophyton, Rhodotorula, and Aspergillus by agar disc diffusion and broth dilution methods. None of the oils showed any activity against the tested bacterial strains, but exhibited moderate-to-strong activity against all fungi with the only exception of A. fumigatus. The highest zone of inhibition was observed in case of Cryptococcus neoformans and Trichophyton interdigitalis

    surfaces. Attrition of teeth (attritio dentium represents teeth wear during mastication, friction on the tooth or teeth during parafunctional mandibular movements (bruxism, but without the abrasive effect. Dental erosion (erosio dentium or corrosive wear is a progressive, irreversible loss of dental hard tissue resulting from the effect of acids and /or chelation in the mouth, but without the participation of bacteria. Acids, of either exogenous or endogenous origin (peptic ulcer, gastritis, or bulimia, anoreksia nervosa, that come into the mouth can lead to different clinical manifestations of erosion depending on the time of exposure, the microstructure of teeth, buffering capacity, the amount of saliva and other factors. The changes are visible on the palatal surfaces of upper anterior teeth and, in severe cases, the lingual surfaces of posterior teeth. Occupational dental erosion occurs during exposure to industrial gases that contain hydrochloric or sulfuric acids, as well as the acids used in galvanizing and manufacture of battery and weapons. Due to the multifactorial nature of erosive tooth wear preventive measures must be applied taking into account chemical and biological factors as well as the patient's behavior associated with the etiology and pathogenesis of erosion. It is recommended to consume food and drinks that stimulate the secretion of large amounts of saliva base; to use neutral or alkaline mouthwash, and to chew sugar-free gum; to apply adequate oral hygiene (soft brushes, non-abrasive tooth paste, proper washing technique and not to consume aciding food and carbonated soft drinks and fizzy drinks in a great amount and frequently. It is necessary to apply preparations with high content of fluoride, and lubricant of tooth wear (powder CaF, CaF mixture and olive oil, and asset-based titanium tetrafluoride and casein-calcium phosphate. Commercial tooth paste that contains CPP-ACP (casein phosphopeptide-amorphous calcium phosphate and calcium phosphate
