Scientific interest in low-molecular-weight pectins is not accidental. Despite the experimental material widely presented in the literature on the pharmacological effects of pectins, the clinical application of the developments has not yet been fully implemented. On the one hand, antitumor potential is registered in polymers with a mass of hundreds of kilodaltons, on the other hand, practically nothing is known about such in pectin derivatives weighing less than 20 kDa. In addition, the issues of assessing the nature of the pharmacological interaction of nanoscale pectin and conventional cytostatics are not covered. The aim of this work is an experimental study of the antitumor potential of low-molecular, low-esterified pectin in combination with a cytostatic agent on a model of Walker’s carcinosarcoma. Pectin therapy of Walker’s transplanted tumor in several series of experiments consistently caused inhibition of its growth from 60% to 80%. The combined use of pectin and cyclophosphane caused inhibition of tumor growth up to 72.4%. The increase in life expectancy in the “pectin + cyclophosphane” group versus the “cyclophosphane” group was 200%. It can be concluded that nanoscale pectin is a promising drug for in-depth study since it meets the criteria of primary screening (increase in animal life expectancy, inhibition of tumor growth, survival without tumor growth).

The prevalence of intra-uterine dysfunction of ductus arteriosus is unknown and the clinical consequences are poorly understood. We report a case of prenatal diagnosis of premature closure of the ductus arteriosus due to maternal intake of metamizole during pregnancy. Fetal echocardiography at 37 weeks of gestation revealed a right ventricular hypertrophy and suspected stenosis of the tricuspid valve. A cesarean section led to an excellent neonatal outcome. The aim of this report is to show echocardiographic abnormalities and outcomes of this rare phenomenom.

Aim of study: In terms of treatment, it is essential to consider the correct use of preservatives and epoxy resin. Lumber pretreated with these substances can protect the wood from biodegradation or insect attack for exceeding three-year life expectation periods.Methods: To further increase durability and structural integrity, Posttreatment like painting or lamination on wood surfaces helps keep moisture out and carries a higher yield compared to traditional methods. In addition, chemical treatments to make timber resistant to fungal infestations as well has been gaining traction recently which makes it possible for lumber to be used in even more applications safely than ever before. Results: Thus, proper treatment plays a major role when considering the implications of using lumber as a resource both structurally and functionally over time. Conclusion: Lumber remains one of the most sought-after resources due to its versatility; likewise finding ways how impart maximum longevity necessitates research into new treatments available so that we can optimally exploit such abundant supplies without compromising the durable nature of good quality timber source.

Hypertrophy of the adenoid is a rare condition in adults, often suspicious of malignancy. We present a case of a 31-year-old female with a clinical presentation of a giant nasopharyngeal mass, clinically suspicious for malignancy, given the size and greyish discoloration. She presented with left-side otalgia, hearing loss, and nasal obstruction. After broad investigations on adenoid tissue following adenectomy, a reassuring diagnosis of adenovirus-related adenoiditis could be made. This case demonstrates the importance of broad microbiological testing in ruling out malignancies. The patient recovered completely. 

Excitation functions (EF) for four reactions of the type 93Nb (α, xn); x = 1-4 were studied. This study provides current evidences about the dominance of pre-equilibrium processes at high energies followed by compound nucleus equilibration at low energies. The main objective of the work is to look pre-equilibrium emission induced by alpha particle energies up to 100 MeV on Niobium through describing, analyzing and interpreting the theoretical results of cross sections obtained from computer code COMPLET by comparing with experimental data obtained from EXFOR library. COMPLET code has been used for the analysis using the initial exciton number n0 = 4(4p+oh) and level density parameter ACN/10. A general agreement was found for all reactions.

Atom has been considered as a space of perfect vacuum and no energy loss takes place inside the atom. The purpose of the current research work is to prove that even fundamental particles receive energy from external sources for their motion. In order to prove this, the model of the solar system and its planets is selected. According to this proposed theory, even the gravitational attraction between planets and stars is due to external energy received through the hypothesized O- Dimension. O-dimension is a time-independent totally symmetric dimension filled with potential energy and it encircles every object from atom to galaxy as well as the whole Universe and imparts energy to the whole Universe. The gravitational force between two objects is a result of the energy shadow cast by them on each other. Mathematical model developed and applied to the Sun and planets in our solar system as well as Earth and moon and it fits with the values obtained by Newtonian theory, confirming the validity of the hypothesis.

Objective: To explore the pathologic response rate to primary progesterone treatment in patients with Endometrial Intraepithelial Neoplasia (EIN) and early-stage endometrioid-type Endometrial Adenocarcinoma (EAC).Methods: Retrospective chart data were collected for patients with either EIN or EAC receiving primary progesterone treatment between 2015 and 2022. The presence of complete or partial response, time to response, and other demographic and treatment factors were recorded to determine independent predictors of response to progestin treatment.Results: In total, 112 women who were diagnosed with EIN or EAC were treated with upfront progestin therapy, of whom 79 had sufficient follow-up to assess response. Fifty patients (63%) responded, of whom 10 (20%) ultimately relapsed. Response was more robust among patients with EIN (79%, n = 33) compared with patients who had cancer (46%, n = 17). The median time to respond was 5.8 months overall. Diagnosis of EIN, younger age at diagnosis, and any pathologic evidence of progesterone effect were all predictors of treatment response. Younger patients had a significantly shorter time to partial or complete response with a median time to response of 5.9 months in patients ≤ 45 and 13.8 months in patients > 45. Conclusion: Our study demonstrated a lower overall response rate (63%) than reported in previous studies, especially for patients with cancer (46%). Younger patients had a significantly shorter time to respond than older patients. Pathologic progesterone effect observed at any time during treatment was a significant predictor of treatment response regardless of diagnosis and could serve as an early predictor of response to therapy.

Background: Ectopic pregnancy (EP) is a common and serious early pregnancy problem with a significant morbidity rate and the potential for maternal death. Women commonly present with minimal vaginal bleeding and abdominal pain.Objective: The main objective of the study was to evaluate the risk factors, clinical presentation, sites, and management outcomes of ectopic pregnancies. Methodology: It was a prospective descriptive, cross-sectional hospital-based study conducted at Bashair Teaching Hospital during the period January 2021–June 2021.An interview questionnaire was used, and eighty-two (82) women were included after informed consent. Demographic and clinical data concerning personal history, symptoms of presentation, risk, site, and type of management were recorded.Results: Ectopic pregnancy incidence was 2% and most risk factors were infection 29.3%, surgery 15.9%, miscarriage 13.4%, infertility 12.2%, tubal surgery 4.9%, previous ectopic pregnancy 4.9%, intrauterine contraceptive device (IUCD) 3.6%, and tubal ligation 2.4%. Women presented with bleeding and abdominal pain at 47.5%, bleeding at 18.3%, abdominal pain at 9.7%, and shock at 8.5%.The sites are ampullary (57.3%), fimbria (9.7%), interstitial (8.5%), isthmus (8.5%), ovarian (7.3%), cervical (4.8%), and abdominal (3.6%).Surgical management was 93.9%, medical and surgical management was 3.6% and medical management was 2.4%. A blood transfusion was received at 37.8%.Conclusion: The study concluded that women of reproductive age are at risk of ectopic pregnancy, so healthcare providers and doctors should have a high index of suspicion, prompt diagnosis, and intervention for ectopic pregnancy. Assessment of women at risk factors and modifications will reduce incidence. 

Cardiac revascularization surgery has a long history. Its results and safety are well known. Nonetheless, the long-term patency rate of certain grafts used in cardiac revascularization is non-optimal, and CABG is associated with a risk of cerebrovascular stroke due to aortic manipulation. We have developed a simple control quality protocol of the anastomosis performed in CABG, aiming to improve the long-term patency of certain grafts used in cardiac revascularization surgery and reduce the risk of cerebrovascular stroke in those patients. 

Introduction: The identification of new markers of thrombotic risk and early diagnosis of Non-ST-segment Elevation Myocardial Infarction (NSTEMI) could allow the optimization of the therapy and predict short and long-term prognosis. Aims and objective: We aimed to assess the impact of Immature Platelet Fraction (IPF) and Mean Platelet Volume (MPV) levels on the extent of Coronary Artery Disease (CAD) in patients with NSTEMI undergoing coronary angiography. Methods: This is a prospective observational study in which 100 subjects of Non-ST Elevation Myocardial Infarction were recruited. For the measurement of platelet count, IPF and MPV samples were analyzed by an automated hematology analyzer (Sysmex XN 1000). Patients were subjected to coronary angiography as per institutional protocol and the extent of coronary artery lesion was noted. Result: A cutoff of MPV (fL) ≥ 10.6 can predict the involvement of the left anterior descending artery (LAD) with a sensitivity of 84%, and a specificity of 50%. With the cutoff of IPF (%) ≥ 2.4, it can even predict the type of disease i.e., Double Vessel Disease (DVD), or Triple Vessel Disease (TVD) with a sensitivity of 97%, and a specificity of 19%. Mean IPF values and MPV levels were significantly higher in patients with LAD involvement i.e., 4.40 ± 1.72% (p = 0.003) and 12.45 ± 1.88 (p = 0.030) respectively than in patients without involvement of LAD i.e., 2.78 ± 1.50% and 11.08 ± 2.19 respectively. Conclusion: Immature platelet fraction and mean platelet volume were significantly associated with the involvement of the left anterior descending artery which was the most commonly involved vessel in patients with NSTEMI. Mean platelet volume was also associated with TVD which was statistically significant. MPV and IPF can be useful early independent hematologic markers to identify patients with a higher risk for significant CAD as they are readily available and inexpensive.
