Maternal thyroid dysfunction and neonatal cardiac disorders

Published on: 27th December, 2017

OCLC Number/Unique Identifier: 7355941189

The normal levels of thyroid hormones (THs; thyroxine, T4 & 3,5,3′-triiodo-L-thyronine, T3) are necessary for the normal development [1-48], particularly the fetal and neonatal cardiac growth and development [49]. The actions of THs are facilitated genomically by thyroid receptors (TRs, α and β) and non-genomically at the plasma membrane, in the cytoplasm and in cellular organelles [4,49-55], by stimulation of Na+, K+, Ca2+ and glucose transport, activation of protein kinase C (PKC), protein kinase A (PKA) and mitogen activated and protein kinase (ERK/MAPK) [4]. In addition, the transport of T4 and T3 in and out of cells is controlled by several classes of transmembrane TH-transporters (THTs) [56], including members of the organic anion transporter family (OATP), L-type amino acid transporters (LATs), Na+/Taurocholate cotransporting polypeptide (NTCP), and monocarboxylate transporters (MCTs) [4,49,57,58]. Adding additional complexity, the metabolism of T4 and T3 is regulated by 3 selenoenzyme iodothyronine deiodinases (Ds: D1, D2 and D3) [59-61]. On the other hand, the congenital hypothyroidism can cause the following [49,62-64], (1) congenital heart diseases; (2) diastolic hypertension; (3) reduced cardiac output, stroke volume and a narrow pulse pressure; (4) dilatation and overt heart failure; (5) elevation in the systemic vascular resistance [65-68]. Similarly, the chronic hyperthyroidism can cause the following [49,64]: (1) cardiac hypertrophy; (2) increase in the cardiomyocyte (CM) length rather than width; (3) noticeable diminution in systemic vascular resistance; (4) elevation in the cardiac contractility; (5) systolic hypertension; (6) increase in the cardiac output, venous volume return, blood volume and pulse pressure; and (7) reduction in the systemic vascular resistance [49,69]. T3-therapy can induce DNA synthesis and cardiomyocyte proliferation, and improve the cardiac contractility; though, this action is as still unidentified [49,70-74].

Head impact exposure comparison between male and female amateur rugby league participants measured with an instrumented patch

Published on: 29th April, 2019

OCLC Number/Unique Identifier: 8163924025

Background: Epidemiological studies report that females experience greater rates of concussion when compared with males. Biomechanical factors may result in greater post-impact head velocities and accelerations for a given force for females when compared with males. Purpose: To quantify the magnitude, frequency, duration and distribution of impacts to the head and body in rugby league match activities for females versus males. Design: Prospective descriptive epidemiological study. Methods: 21 female and 35 male amateur rugby league players wore wireless impact measuring devices (X2Biosystems; xPatch) behind their right ear over the mastoid process during match participation across a single season. All impact data were collected and downloaded for further analysis. Results: Male amateur rugby league players experienced more head impacts than female amateur rugby league players (470 ±208 vs. 184 ±18; t(12)=-3.7; p=0.0028; d=1.94) per-match over the duration of the study. Male amateur rugby league players recorded a higher median resultant Peak Linear Acceleration (PLA(g)) (15.4 vs. 14.6 g; F(824,834)=51.6; p<0.0001; t(1658)=-3.3; p=0.0012; d=0.10) but a lower median resultant Peak Rotational Acceleration (PRA(rad/s2) (2,802.3 vs. 2,886.3 rad/s2; F(831,827)=3.1; p<0.0001; t(1658)=5.7; p<0.0001; d=0.13) when compared with female amateur rugby league players Conclusion: Females recorded lower median values for PLA(g) and Head Impact Telemetry severity profile (HITSP) for all positional groups but had a higher PRA(rad/s2) for Hit-up Forwards (HUF) and Outside Backs (OSB’s) when compared with male HUF and OSB’s. Females also recorded more impacts to the side of the head (48% vs. 42%) and had a higher 95th percentile resultant PRA(rad/s2) (12,015 vs. 9,523 rad/s2) to the top of the head when compared with male rugby league players.

The Influence of Gravity on the Frequency of Processes in Various Geospheres of the Earth. Biogenic and Abiogenic Pathways of Formation of HC Accumulations

Published on: 9th July, 2024

Based on the results obtained in the study of the interaction of geological and biosphere processes, we found out that there is a close relationship between them. It was also found that the gravity of the bodies of the solar system on the Earth plays a significant role in the above relationship. The effect of gravity was demonstrated on the movement of lithosphere plates, on the processes in the atmosphere and hydrosphere, on related climatic cycles, and the biosphere processes, including "living" organisms' evolution and their mass extinctions. The periodicity of these processes due to gravity is shown. It is expressed in the alternation of short-term orogenic periods of the beginning of the processes with long-term geosynclinal periods of their development and completion. Both periods constitute the repetitive orogenic cycles. The relationship of the cycles with the evolution of photosynthesis, as well as with related Organic Matter (OM) accumulation in sediments after mass extinction of organisms, including OM transformation leading to the formation of Hydrocarbon (HC) accumulations, is shown. Biogenic processes accounting for the accumulation and transformation of organic matter in sediments constitute the biogenic pathway of the formation of hydrocarbon accumulations. It is shown that the influence of gravity extends to the processes in the inner geospheres, including the movement of magma in the asthenosphere under the lithosphere shell, to the movement of hydrogen gas coming from the Earth's core, combining with volatile compounds of elements present in magma, as well as to the rifting process. It is shown that rifting processes lead to the formation of gaseous HC accumulations and constitute a pathway called abiogenic. The obtained results shed light on the peculiarities of the formation of HC accumulations by biogenic and abiogenic pathways, allowing prediction of their chemical characteristics. This is essential when searching for oil and gas and planning exploration works.

Changes in the frequency and intensity of Tinnitus using the Suppressive Noise Spectrum

Published on: 21st July, 2017

OCLC Number/Unique Identifier: 7325433767

Objective:To report findings of improvement in patient tinnitus intensity and changes in frequency using a novel suppressive noise spectrum. Design: Single-subject; each subject served as his or her own control. Each patient received treatment, and changes were measured over time. Setting: Tertiary referral via university otolaryngology and hospital audiology as well as audiology clinics in the region. Patients: Fifteen tinnitus ears in 8 patients. Interventions: Therapeutic and rehabilitative. Main Outcome Measures:: Tinnitus frequency, tinnitus intensity, and tinnitus questionnaire. Results (Findings): After 3 months of exposure to the customized suppressive noise spectrum therapy, patients showed a shift in tinnitus frequency in addition to a significant decrease in tinnitus intensity from the pre-treatment to post-treatment condition (p<0.05). Typically, improvement was gradual based on comparing 3 sets of data collected at baseline, 1.5 months and 3 months. Conclusion: Using suppression in tinnitus is novel. Based on our findings, using a customized suppressive noise spectrum is effective in shifting the frequency, reducing the intensity of subjective tonal tinnitus, and improving the handicap based on THQ test. From this seminal report, factors related to maximizing its effectiveness (e.g., length of listening time, level of hearing loss, and application for alternative tinnitus types) may be considered for future research.

Design and Construction of Automatic Facemask and Body Temperature Scanning Entry Barrier Machine

Published on: 10th July, 2024

In the context of the global pandemic, public health screening has become paramount as the whole world including developed countries is going through a health crisis. A face mask prevents transpiration and protects against airborne transmitted bacteria or viruses. In the previous scenario of coronavirus, it was critical to eradicate this sickness and preserve our lives. Hence, prevention is better than cure becomes true. Accordingly, many precautionary measures were taken to reduce the spread of the virus. One such method of prevention is wearing a mask and regular monitoring of body temperature. This research dealt with the design and construction of an automatic entry barrier machine that integrates both facemask detection and scanning of individuals exhibiting elevated body temperature functionalities without any human interference. This was accomplished by simulating and synergizing a microprocessor (Raspberry Pi 3 Model B+), a Pi camera, an Infrared Non-contact Temperature sensor, a servo motor, and other components. The barrier arm opens and allows entrance at normal temperature by indicating a green light, displaying ‘allow’ on the LCD, and signaling once or preventing entrance at an elevated unacceptable temperature by indicating a red light, displaying ‘not allowed’ on the LCD, and signaling five (5) times.

B-ultrasound-guided Intrahepatic Infusion of Autologous Bone Marrow Cells for Decompensated Cirrhosis

Published on: 12th July, 2024

Objective: To study the therapeutic effect of B-ultrasound-guided intrahepatic infusion of autologous bone marrow nucleated cells on decompensated cirrhosis. Methods: To observe the clinical treatment of 75 cases of decompensated cirrhosis. Among them, 30 cases received routine liver protection and diuretic treatment. 45 cases were treated by percutaneous transhepatic infusion of autologous bone marrow nucleated cells under the guidance of B ultrasound. There were no significant differences in liver function and blood routine indexes between the two groups before treatment (p > 0.05). Results: The indexes of liver function and blood routine at different time periods of 1 month, 3 months, 6 months, and 12 months in the conventional treatment group did not change significantly. 6 cases died of liver failure within 1 year, the fatality rate was 20%. The indexes of liver function and blood routine of percutaneous liver transhepatic infusion of autologous bone marrow nucleated cells at 1 month, 3 months, 6 months, and 12 months under the guidance of B-ultrasound were significantly better than those of the conventional treatment group (p < 0.05). One case died of gastrointestinal bleeding in the group of percutaneous transhepatic infusion of autologous bone marrow nucleated cells guided by B ultrasound, with a fatality rate of 2.5%. Compared with the conventional treatment group, there were significant differences (p < 0.05). Conclusion: Conventional drug therapy has no obvious effect on decompensated cirrhosis. Intrahepatic infusion of bone marrow nucleated cells can significantly promote liver function reconstruction in decompensated cirrhosis.

Post-catheterization Common Femoral Artery Pseudoaneurysm in a Patient with a Mechanical Mitral Valve Requiring Anticoagulation: A Case Report

Published on: 15th July, 2024

Iatrogenic femoral pseudoaneurysms are a rare complication of transfemoral vascular access. We present a case of a 65-year-old woman with a mechanical mitral valve requiring warfarin, who developed a femoral pseudoaneurysm four days after cardiac catheterization with femoral access. The patient developed a 17 x 10 x 17 cm rectus sheath hematoma and was treated with ultrasound-guided thrombin injection. Anticoagulation was held for three days while the patient was monitored for further bleeding and later restarted based on shared decision-making, given the risk of valve thrombosis. There are few guidelines regarding the re-initiation of anticoagulation in high-risk bleeding patients with mechanical mitral valves. Non-invasive coronary computed tomography angiography should be considered in patients on anticoagulation who require non-emergent cardiac ischemic evaluation.

Recent approach to incorporate tellurium in metal carbonyl cluster utilizing extrusion reaction

Published on: 26th November, 2019

OCLC Number/Unique Identifier: 9269425535

The incorporation of tellurium into metal carbonyl using tellurium transfer/ extrusion reaction is presented in this work. The results bring one of the new ways to incorporate tellurium by transferring it from one molecule to another molecule, in comparison to the work so far where either insertion or extrusion reactions were shown. The reactions of PhC2TeC2Ph with the metal carbonyl cluster produced thermodynamically stable metal carbonyl tellurium clusters.
