Diagnostic Criterion

Morphological diagnosis of endogenous intoxication in target organs - lung, liver and kidney, is unreliable due to lack of specific structural changes. To reliable diagnose of intoxication, the definition used in the tissue of the target organ indole, phenol and skatole, which are products of the activity of intestinal bacteria and penetrating into the systemic circulation together with bacterial lipopolysaccharide, can be used. The diagnostic accuracy can be estimated by reducing the brightness of the color micrographs of the investigated histological preparations in the system brightness RGB in the analysis of the micrographs in the program "Adobe Photoshop".Endogenous intoxication causes a statistically significant increase in the number indianola products, verified by the reaction of diazotization on histological sections in the cytoplasm of cells of the lungs, liver and kidneys. It can serve as a reliable diagnostic criterion for post-mortem morphological diagnosis of endogenous intoxication. The accumulation of indole, phenol and skatole in millionary partitions is detected at the endogenous intoxication in the lungs. In the liver, the toxic products found throughout the liver lobules. In the kidneys, indianola products accumulate in remoteley proximal tubules. Diagnostic value of research to target organs within the definition disapoiting substrate decreases in the series: liver>kidneys>lungs.

Сondition of hair reflects changes in metabolism in animals and humans in relatively long period of time. Thus, the study of hair of domestic dogs with different variants of pathology, in particular nephropathy and polyorgan pathology of liver and kidney is relevant and appropriate in terms of differential diagnosis and establishment of little-known links in the pathogenesis of diseases of these organs. The aim of this study was to establish the diagnostic meaning of «cuticular index» of sick dogs. The object of the study was 60 dogs with confirmed diagnoses. The animals were examined by general clinical methods (temperature, pulse, and respiratory rate were determined) and blood was taken from the jugular vein for biochemical research. Hair samples were obtained and the «cuticular index» was determined. Examination of the cuticle was performed using prints on a colorless varnish, which was applied to a glass slide, pressing the hair to the varnish layer. Then, when the varnish hardened, the hair was removed by the edge from the peripheral end. The impression was studied under a microscope (in. x 400) and set the value of «cuticular index» in the root zone, in the thickest part of the hair shaft, expressed in μm2. Based on the results obtained during clinical and laboratory studies, we have formed groups of sick dogs, which became the basis for studying the dynamics of the «cuticular index» (CI). It was found that in different variants of nephropathy and in the development of hepatic-renal and renal-hepatic syndromes in dogs, significant structural changes occur in the liver and kidney, which correspond to violations of metabolic processes determined by the results of clinical microscopic and biochemical blood tests, as well as changes in the area of the outer surface of the cells of hair cuticle, which we have defined as the «cuticular index». The method of determining the «cuticular index» can be used in differential diagnosis of kidney and liver pathology in combination with clinical, instrumental and laboratory studies, as well as for dispensary examination of animals. The article provides examples of various variants of pathology with the definition of «cuticular index»

Gastric cancer is the world's second-largest death cause. Developing suitable medical therapies can help individuals live longer. So far, GC treatment has depended on several pharmaceutical techniques. Chemotherapy and surgery are GC patients' most frequent treatment choices. The most major hurdles to effective GC therapy are chemotherapeutic resistance and non-selective targeting. Recent GC-targeted therapeutic research has focused on building more selective and effective anti-GC pharmacological approaches. Because molecular focused therapy can greatly exacerbate the current inefficacy of normal GC therapy procedures, peptide base synthesis can be used as a carrier to deliver radiation or other fatal chemicals to tumor locations with precise protein overexpression. Different types of peptides with special binding affinity to GC overexpressed receptors have been identified for targeted therapy and imaging. Although some of these peptides have excellent GC targeting ability, they also need great GC penetration capacity and no systemic in vivo toxicity before they can be employed in clinical studies. One of these peptides' most notable limitations is their short plasma half-life, limiting their efficient delivery to tumor locations. Sluggish binding pharmacokinetics, along with in vivo instability, can produce targeted treatment failure. Using an appropriate modification strategy to boost blood circulation time may be advantageous.The key to producing successful, innovative anti-cancer targeting drugs with specific targeting capabilities is to mark the peptide with distinct diagnostic and therapeutic radioisotopes. Although a peptide's radiolabeling or enzymatic degradation may not affect its targeting capabilities, the radiation dose delivery impact on it is obvious. Selecting an appropriate type of radionuclide to achieve high-specific activity, using a simple and high-efficiency radiolabeling process, and selecting an adequate spacer and chelator to manage peptide biodistribution are all important considerations when designing a peptide-based radiopharmaceutical. High internalization and significant systemic circulation washout are other essential tumor targeting needs. Many of the peptides described in this work lack these critical features. The radiolabeled peptide should also remain intact and have a short blood washout period, allowing targeted imaging and therapy. SPECT and PET are the most extensively used technologies in nuclear medicine. Although PET has a greater resolution, SPECT technology gives a comparable sensitivity at a lesser cost. Combining fast binding pharmacokinetics with suitable stability in vivo can result in efficient tumor contrast. Non-target liver and kidney accumulation is required when employing radiolabeled peptides to target GC. When a radiolabeled peptide accumulates more in the liver and intestine than in the GC tumor, the image quality degrades. However, using the proper chelator and spacer can assist decrease non-target accumulation in the kidneys. Finally, considering all these conditions and being positive, it is conceivable to produce a unique peptide with avid binding to GC cells.

A histologic examination of spontaneous cases of sawdust livers in cattle indicated that the focal liver necrosis was an expression of vitamin E-selenium deficiency. The condition was reproduced in Hereford steers by feeding a diet rich in polyunsaturated fatty acids and poor in protein, vitamin E. and selenium. Lesions also occurred in the kidney, heart, skeletal muscled and pylorus. Addition of dictary protein or injection of selenium partially prevented the condition. Cellular anoxia with formation of hyalinc bodies in the liver and kidney was considered to be the common denominator of the degenerative changes. Due to the relatively mild tissue changes, plasma GOT and OCT determinations were found to be of no diagnostic value.

Background: Central hypogonadism (CH) is a syndrome characterized by low levels of peripheral sex steroid hormones due to the lack of central (hypothalamic-pituitary) regulation of reproductive system. In females, CH clinically manifests by amenorrhea, anovulation, and infertility. The classical diagnostic criteria of CH in the absence of organic disease of hypothalamic-pituitary region (“idiopathic” CH) include low gonadotropin levels; however, their levels within the reference ranges do not exclude CH. Moreover, reference ranges for these parameters are different between laboratories. Thus, currently no clear laboratory diagnostic criteria for female CH are available.Aim: To determine the diagnostic value of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) basal levels for the confirmation of CH diagnosis in women and to identify cutoffs of basal gonadotropins levels, which can be considered as diagnostic criteria for female CH.Materials and methods: This cross-sectional study included 87 women: 49 with confirmed CH, aged 18 to 36 years (median, 24 [Q21; Q29]), and 38 healthy fertile women with regular menstrual cycles aged 21 to 45 years (median, 23 [Q23; Q28]). In all subjects, LH, FSH, estradiol, testosterone, prolactin, and free thyroxin levels were measured by chemiluminiscent immunoassay.Results: LH, FSH, estradiol, and prolactin levels in the CH patients were significantly lower than those in healthy subjects. The ROC analysis showed that LH level ≤ 1.95 ME/l indicated the central genesis of hypogonadism with sensitivity of 81.25% and specificity of 91.89%. Basal FSH level ≤ 5.075 ME/l had a 70.00% sensitivity and 77.14% specificity for CH diagnosis.Conclusion: Basal LH level ≤ 1.95 ME/l measured by chemiluminiscent immunoassay can be considered as an idiopathic CH diagnostic criterion in female with amenorrhea due to the hypoestrogenemia with sensitivity of > 80% and specificity > 90%.

In Parkinson’s disease (PD), some structural changes in the retina have been shown using optical coherence tomography (OCT). Among them most attractive are atrophic changes in retinal nerve fi ber layer (RNFL). However, diagnostic signifi cance of the OCT method in PD remains debatable. Objective: to investigate a thickness of RNFL in Parkinson’s disease patients and to determine the signifi cance of the OCT method in the PD diagnostics. Materials and methods. In PD patients (n = 24) and in a control group (n = 20) OCT was used to study the thickness of RNFL — average, in quadrants and in 10 sectors. Results. In patients with PD thinning of RNFL in the inferior quadrant was revealed (p = 0.009). The sensitivity and specifi city of the method were 56% and 82%, respectively. The thickness of RNFL was not associated with parkinsonian symptoms asymmetry, duration and severity of the disease. In the control group and in PD patients, there was a relationship between the RNFL thickness and age. Conclusion. PD is characterized by atrophic changes in the retina in the form of thinning of RNFL in the inferior quadrant, which confi rms the systemic nature of neurodegenerative pathology in this disease going beyond the substantia nigra and brain tissue. At the same time, the thickness of RNFL showed limited diagnostic value for detecting PD cases.

Systemic hypertension is a common disorder, primarily affecting older cats. Most cases are secondary to underlying medical conditions, such as chronic kidney disease. If left untreated, systemic hypertension has the potential to cause serious damage to certain target organs and can be fatal. Target organs include the nervous system, cardiovascular system, eyes and kidneys. Target organ damage to the eyes is often pathognomonic and is detected on ophthalmological examination in up to 80% of cats with systemic hypertension. Blood pressure measurement is essential in confirming a diagnosis and should be prioritised in cats showing evidence of target organ damage. Blood pressure screening of apparently healthy older cats is justified, since the risk of hypertension increases with age. Systemic hypertension is diagnosed in cats with persistent elevation in their systolic blood pressure of 160 mmHg or higher. Stress and anxiety can cause a transient increase in systolic blood pressure so measurements should be collected in a manner that is as calm and ‘cat friendly’ as possible. In the presence of confirmed target organ damage, a single high systolic blood pressure reading confirms systemic hypertension. Where no target organ damage is detectable, evidence of elevated systolic blood pressure on two or more occasions is needed to confirm the diagnosis.

The inhalation of metal (including lead) nanoparticles poses a real health issue to people and animals living in polluted and/or industrial areas. In this study, we exposed mice to lead(II) nitrate nanoparticles [Pb(NO3)2 NPs], which represent a highly soluble form of lead, by inhalation. We aimed to uncover the effects of their exposure on individual target organs and to reveal potential variability in the lead clearance. We examined (i) lead biodistribution in target organs using laser ablation and inductively coupled plasma mass spectrometry (LA-ICP-MS) and atomic absorption spectrometry (AAS), (ii) lead effect on histopathological changes and immune cells response in secondary target organs and (iii) the clearance ability of target organs. In the lungs and liver, Pb(NO3)2 NP inhalation induced serious structural changes and their damage was present even after a 5-week clearance period despite the lead having been almost completely eliminated from the tissues. The numbers of macrophages significantly decreased after 11-week Pb(NO3)2 NP inhalation; conversely, abundance of alpha-smooth muscle actin (α-SMA)-positive cells, which are responsible for augmented collagen production, increased in both tissues. Moreover, the expression of nuclear factor κB (NF-κB) and selected cytokines, such as tumor necrosis factor alpha (TNFα), transforming growth factor beta 1 (TGFβ1), interleukin 6(IL-6), IL-1α and IL-1β , displayed a tissue-specific response to lead exposure. In summary, diminished inflammatory response in tissues after Pb(NO3)2 NPs inhalation was associated with prolonged negative effect of lead on tissues, as demonstrated by sustained pathological changes in target organs, even after long clearance period.
