Published: August 2021

Aim. To assess the number of markers of apoptosis and cell proliferation, as well as their relationships in the area of restenosis of arterial reconstructions.
Methods. The study included 14 patients with a diagnosis of arteriosclerosis obliterans of the lower extremities. Post-thrombotic occlusion of femoropopliteal bypass. All patients were males with stage III disease according to the Fontaine classification modified by A.V. Pokrovsky. The average age of the patients was 653.4 years. The mean disease duration was 92.5 months after the initial intervention. Intraoperative material distal anastomosis of femoropopliteal bypass was taken from patients during arterial reconstructions. As a control, we used arterial wall samples obtained at organ procurement from postmortem donors without arteriosclerosis obliterans of the lower extremities. The number of samples is 8. The site of their collection is the popliteal artery. After sampling, they were crushed, and a homogenate was prepared, followed by the determination of the amount of p53, PDGF BB, Bcl2, and Bax proteins using the enzyme immunoassay. Statistical analysis was performed using the Statistica 10.0 software. Group differences were assessed by using the MannWhitney test. Correlation coefficients were determined using the Spearman test. Data are presented as medians and interquartile ranges.
Results. In tissue samples of restenosis, the amount of p53 protein was 0.07 units/mg and was significantly reduced compared with the control samples 0.14 units/mg (р=0,015). The amount of platelet-derived growth factor PDGF BB was 0.17 ng/mg (р=0.05), Bcl2 1.61 ng/mg (р=0.008), Bax 6.0 ng/mg (р=0.25) in the restenosis area and was increased in comparison with the control samples (0.04 ng/mg, 0.9 ng/mg, 4.4 ng/mg, respectively). A relationship between p53 and platelet-derived growth factor BB (r=0.724, p=0.002), platelet-derived growth factor BB and Bcl2 (r=0.672, p=0.003) was revealed in samples from restenosis tissue obtained during arterial reconstructions.
Conclusion. The decreased apoptosis, expressed in a low level of p53 protein, with an increased Bax/Bcl-2 ratio is associated with an increase in the proliferative response of vascular wall cells in the area of restenosis of arterial reconstruction.

Published: August 2021

Aim. To improve the results of the surgical component in the treatment of a nodular form of breast cancer with lateral and central localization by analyzing hemoglobin oxygen saturation of arterial blood in the foci of breast cancer, regional lymph nodes and resection line of the breast.
Methods. The study involved 175 patients with a nodular form of breast cancer with lateral and central localization (T23N12M0), including 86 in the main group and 89 in the comparison group. In the main group, hemoglobin oxygen saturation in arterial blood of the foci of breast cancer, parenchyma, pectoral muscles and regional lymph nodes was examined for spread of cancer during surgery for nodular breast cancer by using a device developed by us (patent RU 2581266). This examination was not performed in the comparison group. Histopathological examination of resection specimens revealed confirmation of the main foci of breast cancer and the presence of metastases in the regional lymph nodes and pectoral muscles of the breast. Statistical analysis of the data was performed by using the Statistica 10 software. The arithmetic mean, the standard error of the mean and the standard deviation were calculated for the quantitative indicators.
Results. In the main group, 86 patients had no recurrence and metastases in the follow-up, while in the comparison group, cancer recurrence was identified in 89 patients and metastases was found during cytological and histological studies in 9 patients.
Conclusion. Determination of hemoglobin oxygen saturation of arterial blood during surgery in the subclavian, axillary and subscapular lymph nodes as well as in the pectoralis major and minor muscles allows clarifying the distribution of breast cancer, specifying the scope of the operation and improving the results of the surgical component of breast cancer treatment (T23N12M0).

Published: August 2021

Aim. To conduct a clinical and economic analysis of the effectiveness of the program fissure sealing of first permanent molars with fluorine-containing sealants among schoolchildren of 78 years old in six cities of the Republic of Tatarstan.
Methods. Between 2007 and 2011, dentists of six cities of the Republic of Tatarstan performed fissure sealing of permanent first molars using a fluorine-containing sealant in 24,394 schoolchildren aged 78 years according to the manufacturer's instruction. A clinical assessment of fluorine-containing sealant retention during tooth eruption was carried out annually, the results were submitted to the organizational and methodological office of the Republican Dental Clinic. The analysis of the complex of signs that have a normal distribution and characterize four degrees of sealant retention on the occlusal surfaces of teeth in children from several cities was carried out by using one-way ANOVA (analysis of variance) with the calculation of a p-value and F-test (according to Ronald Fischer). Statistical data processing was performed using the Microsoft Office Excel 2017 software. The economic analysis was performed by using mathematical modelling.
Results. The use of sealants at the age of 78 years ensured the complete safety of the sealant in 80% of children; the development of dental caries in 1.7%; complete and partial loss 14.3%; disturbance of fit without the development of caries in 4.1% of cases [р=0.0095 (0.01); f-test 3.09839]. Clinical and economic analysis using a mathematical hypothesis in sealing with a fluorine-containing composite sealant determined the preservation of the conditionally spent funds for the treatment of 80% of healthy teeth for 4 years of the project in the amount of 6,001,177 rubles. Notional saved costs for the treatment of one tooth with a sealant amounted to 23.7 rubles.
Conclusion. Implementation of the program fissure sealing of first permanent molars with fluorine-containing sealants among schoolchildren of 78 years old allows a total of 98.3% of healthy teeth to be preserved and notionally saved costs of sealing fissures to be reduced.

Published: August 2021

Aim. To evaluate the treatment outcomes of patients with non-muscle invasive bladder cancer by using transurethral resection alone, transurethral resection combined with electrovaporization and transurethral resection with preliminary tumor fulguration.
Methods. The analysis of the treatment outcomes of 81 patients with non-muscle invasive bladder cancer (TaT1N0M0) in the urological clinic of Kazan State Medical University between the period 2000 and 2016 was carried out. The mean age was 6310.8 years. The patients were divided into 3 groups. The first group included 28 patients who underwent transurethral resection as monotherapy, the second group 26 patients underwent transurethral resection combined with electrovaporization, and the third group 27 patients underwent transurethral resection with preliminary tumor fulguration.
Results. In the group of patients who underwent transurethral resection only, recurrences outside the resection zone occurred in 8 (28.57%) patients, recurrences in the resection zone were detected in 6 (21.43%) patients, and tumor progression was diagnosed in 3 (10.71%) patients. In the group of patients who underwent transurethral resection combined with vaporization, recurrences outside the resection zone were diagnosed in 6 (23.08%) patients, recurrences in the resection zone were detected in 4 (15.38%) cases, and tumor progression was detected in 2 (7.69%) patients. In the group of patients who underwent transurethral resection with preliminary tumor fulguration, recurrences outside the resection zone were diagnosed in 4 (14.81%) patients, in the resection zone in 6 (22.22%) patients, tumor progression in 2 (7.41%) cases.
Conclusion. Transurethral resection alone is not a radical treatment of non-muscle-invasive bladder cancer; transurethral resection combined with vaporization slightly increases the radicality of treatment; transurethral resection with preliminary fulguration reduces the recurrence rate, ensuring the prevention of implant recurrence.
Dual pigtail intervention in acute necrotising pancreatitis

Published: August 2021

Acute pancreatitis has multiple aetiologies. Acute pancreatitis is divided into interstitial oedematous pancreatitis or necrotizing pancre­atitis based on morphology. According to the revised Atlanta classification necrotizing pancreatitis is further sub­divided into acute necrotic collec­tion if the disease develops within 4 weeks or walled-off necrosis if the disease develops after 4 weeks.We report a case of 40years male, with acute pancreatitis for 1 month, presenting with decreased appetite, loss of weight, and tremors of extremities. CT featured active necrotizing pancreatitis with peripancreatic necrosis, collections, and superadded infection which was drained by percutaneous pigtail catheter.Percutaneous pigtail insertion controls the symptoms and this procedure is effective in the management of patients with necrotizing pancreatitis. It serves as definitive or intermediate therapy to surgical necrosectomy in patients who are unfit for surgery. Percutaneous pigtail insertion can be done following a peritoneal or retroperitoneal approach, both approaches have different advantages and it is the choice of the radiologist and the location of the residual collections. The disadvantages are duct leak and it needs multiple check CT’s but in well trained and experienced hands the disadvantages are minimized. Percutaneous pigtail insertion is an alternative approach in the management of necrotizing pancreatitis when the patient is seriously ill or unfit for surgery. It can prevent life-threatening complications and it can be considered as a primary modality in treating a patient with walled-off necrosis.Percutaneous pigtail insertion an alternative approach in the management of necrotizing pancreatitis when the patient is seriously ill or unfit for surgery can be considered as the primary modality of choice in treating patients with walled-off necrosis of the pancreas.

Tamaño y difusión. Construcciones antirracistas en alta resolución para medios peruanos
Authors: Solís López Augusto Pavel 
Published: August 2021

Este ensayo reflexiona sobre cómo la alta definición digital de nuestras pantallas es un fenómeno que conjuga con la noción de racismo simbólico a través de la construcción de experiencias placenteras de marcas audiovisuales. Ello sucede porque el HD va sujeto a estructuras neoliberales digitales que llevan a obtener ingresos y fidelidad, pero que construyen paradojas de autorregulación y estructuras racistas inmutables. La interacción de los medios, los productores y las audiencias se ampara en lo que se ha nombrado ignorancias audiovisuales, creencias falsas o ausencia de creencias reales que se condicen con prácticas antirracistas cuestionables que sitúan el problema racista en lo circunstancial, sin llegar a reconfiguraciones críticas ni estructurales.
Early Weaning of Asian Stinging Catfish, Heteropneustes fossilis (Bloch) Larvae
Authors: Kumar Aditya , Pradhan P.K. , Mohindra V. , Tiwari V.K. , Chadha N.K. , Sood N. 
Published: August 2021

Background: Heteropneustes fossilis commonly known as stinging catfish is a popular indigenous fish of the Indian sub-continent. The species has a high consumer demand because of its tender flesh, low fat and high iron content, and is recommended for anaemic patients. Although the species has high consumer preference and potential for commercial aquaculture but, high mortality of larvae and difficulties in accepting compound diet during larviculture are some of the major bottlenecks. Keeping this in mind, the present study was designed to determine the earliest age at which stinging catfish can be weaned to an artificial diet. The information generated from the present study would be very helpful in improving survival during larval rearing. Methods: The larvae were randomly distributed @ 60 larvae/ tank in 21 circular FRP tanks containing 30 L water each and the feeding experiment started at 2 dph. Seven different feeding strategies depending on the type of food (zooplankton, Artemia nauplii, or microdiet) and the age at which those food items were provided to larvae, were evaluated. Result: The results indicated that larvae survival in the groups weaned after 5 days post hatch (dph) was similar to that of those fed solely with Artemia nauplii and zooplankton, although growth of larvae in the weaned groups was less. As larval growth can be compensated at later stages of the rearing process, therefore, larval survival is considered as one of the most important parameters for evaluating the weaning success. Based on the present findings, it is suggested to rear stinging catfish larvae with zooplankton without dependence upon costly Artemia nauplii, and larvae may be weaned to artificial diet after 5 dph. The findings would be very helpful for improving larval rearing of this indigenous catfish species in Indian rural areas.

Published: August 2021

Background: The success or failure of spawning in any population affects the fishery. Hence, studies on spawning, maturation, fecundity and length at first maturity become essential in drafting management strategies. The detailed information on reproductive traits of Sphyraena obtusata will be helpful in sustainable management and conservation in the study area. Methods: Three hundred and fifty five specimens of S. obtusata were collected fortnightly from Mangaluru and Malpe fishing harbors during August 2019 to March 2020. Maturity of gonads was examined by macroscopic and histological investigations. Spawning periodicity was worked out based on maturity stages and seasonal gonadosomatic index. Gravimetric method of analysis was employed to evaluate the fecundity from randomly collected samples of gravid females. Result: Overall sex ratio revealed that the population had significantly higher (p less than 0.05, X2 test) proportion of females than males. The length at 50% maturity (Lm50) for females and males was estimated at 21.1 and 21.5 cm respectively. The gonadosomatic index (GSI) and the availability of matured individuals for both the sexes in various percentage indicated a prolonged breeding period from October to March with peaks in November and December. The absolute fecundity varied from 91,942 eggs (20.0 cm TL) to 1,34,445 eggs (27.0 cm TL) with an average of 1,12,878 ± 2,984 hydrated oocytes per female.

The urban Tlemcenian glottal stop in a prospective coma due to contact and accommodation: A cross-sectional investigation
Authors: Hammoudi Khadidja 
Published: August 2021

Although many researchers have attempted to include age as a variable in explaining linguistic variation, the delicate mechanisms via which variability in speech relates to age-grading aspect are still incomplete in especially lesser-known Arabic-speaking communities akin to Tlemcen, an urban city in Algeria. This paper aims at cross-sectionally investigating the sociolinguistic situation occurring in the Tlemcen speech community especially concerning the use of the glottal stop, an urban realisation of classical Arabic qaf. With the help of a survey interview, questionnaire and non-participant observation, data were collected from a convenient sample of 122 participants of different age cohorts and genders from Tlemcen. The results show that the dialect contact taking place in the community is moving towards aspects of koineisation, mainly levelling and simplification. Social and psychological features are said to explain the dialectal ruralisation guided by post-adolescent and young male native urban dialect speakers, while females of all ages, including old people, are strictly preservative.

Keywords: Accommodation, age, dialect contact, glottal stop, Tlemcen, speech community.
