To expand the spectrum of used radiopharmaceuticals, it is proposed to obtain a positron-emitting isotope of technetium 94mTc. The intention of this work is to research the possibility of producing various technetium isotopes on a medical cyclotron. For this purpose, we carried out a series of irradiations of an aqueous solution of molybdenum of natural isotopic composition with protons of 11 MeV energy. After technetium isolation, results were analyzed on a γ-spectrometer. 511 keV gamma-ray line was obtained.

Introduction: This study aims at evaluating selected linear anthropometrics of three Nigerian ethnic groups to provide baseline data for the creation of 3D Negroid anatomic models.Methods: The research design was a cross-sectional design. The sampling technique was multistage proportionate random sampling. The places of study were Imo, Oyo, and Kano States of Nigeria. The study lasted for one (1) year. Random selection of 1500 adult males from three major tribes (500 Igbo, 500 Yoruba, and 500 Hausa between the ages of 18 and 40 years). Tukey’s Post Hoc test of multiple comparisons was carried out to determine the specific ethnic groups that differ in specific anthropometric parameters.Results: The differences in standing height, arm length, and thigh length across the Hausa, Igbo, and Yoruba ethnic groups are statistically significant (p < 0.05). Conclusion: The study concluded that the Igbo and Yoruba groups had higher standing heights compared to the Hausa group. Arm length was longer in the Igbo and Yoruba groups compared to the Hausa group. However, thigh length was greater in the Hausa group compared to both the Igbo and Yoruba groups, while the Hausa group had longer thigh lengths than both the Igbo and Yoruba groups. The Igbo group displayed the largest arm span, whereas the Hausa group had the widest shoulder breadth. However, the Hausa group had a lower bi-iliac breadth in comparison to the other two ethnic groups.
With the integration of mobile systems into daily life, social media applications used especially on Android and iOS platforms contain a significant amount of sensitive information. Social media applications on mobile systems have huge personal and sensitive content. Therefore, it is important to design effective techniques for forensic analysis of social media applications and to detect personal data. In this research, three different paid mobile forensic software and 4 different brands and models of smartphones with different operating systems were used and analyzed. The study shows that private messages, e-mails, time information, shared data, location and time information, and other personal data can be obtained by a forensic expert who performs an examination, and it is seen that one software can access the deleted data, but another software cannot access it. In proportion to the technology used in today’s world, mobile forensics incidents are increasing day by day, and a competitive environment is created among the software used to illuminate these incidents. With this competition, software companies dealing with forensic informatics are trying to obtain different data to illuminate forensic events that may occur due to the active use of social media accounts with the developing technology, and software that does not meet the needs in the face of this situation remains in the background. The criminal elements in the investigation areas of mobile forensics differ daily, and the scope of crimes in the virtual environment is expanding with the developing technology. Therefore, mobile forensic analysis applications should be successful in social media applications other than standard data.

Background: One of the problems in vitro fertilization (IVF) treatment for infertility is the high frequency of embryo developmental arrest in the preimplantation stages. Arrested embryos were not selected for transfer and were usually discarded. Case report: We present a case of clinical pregnancy and live birth following IVF treatment and transfer of one arrested embryo. A 31-year-old woman with unexplained infertility underwent IVF treatment. Using the IVF procedure, 7 embryos were produced which were frozen on day 3. In order to embryo transfer in the blastocyst stage, two embryos were thawed and cultured for 2 days. After thawing, one of them was not suitable for transfer and another embryo was arrested at the 10-12 cell stage. Discussion: The Clinical pregnancy and live birth happened after the transfer of an arrested embryo on day 5.Conclusion: This case showed that arrested embryos may resume growth after the transfer to the uterus and result in a successful pregnancy and live birth.
Many studies from the early 20th century on the significance of the pores of Kohn were assessed based on the pathogenesis and pathology of pneumococci pneumonia occurring in man. The pneumococci were carried in the edema fluid directly from alveolus to alveolus through the pores of Kohn and from bronchiole to bronchiole as a result of repeated aspirations, aided by breathing, coughing, and gravity. With the emerging minimally invasive and non-invasive techniques experimentations and the current medications; tackling exacerbations and improving the pulmonary function in various lung diseases remains a dilemma for clinicians and researchers. In this article, we aim to review specifically the pores of Kohn as this is the portal for the spread of infection but also lung recruitment during breathing.
Pneumomediastinum (mediastinal emphysema) is an uncommon condition characterized by the accumulation of air or gas in the mediastinum. Here is a case of a 16-year-old female known to have depression who presented to the emergency department with complaints of shortness of breath, restlessness, chest discomfort, and hoarseness of voice for 2 days. She was initially diagnosed with panic attack, and later on clinical examination, surgical emphysema over the right supraclavicular area was noticed. Chest X-ray was found to be normal, and further imaging with high-resolution computed tomography (HRCT) of the thorax showed pneumomediastinum. In this report, the clinical presentations, radiological features, and management of pneumomediastinum will be discussed.
Long COVID can be defined as a set of symptoms appearing more than 28 days after a documented acute COVID-19. Among them, extreme fatigue and troubles of moods are the most common. To verify that acupuncture can efficiently alleviate long COVID, a chronic disease partly escaping to other treatments, especially fatigue and troubles of mood. To collect data pertaining to the patients included in the study as described in the STROBE guideline. To diagnose the clinical conditions of the patients using the Nan jing in order to choose the meridian and the points to be toned or dispersed depending on the observation of tongue and pulse. Acupuncture can greatly improve the troubles of patients suffering from long COVID after a reduced number of sessions (1 to 4).
This paper examines the effects of globalization on nations, focusing on economic, social, and cultural dimensions. It analyzes the roles of protectionism and globalization in shaping consumer welfare and producer earnings through qualitative methods and the Customs Union theory framework. The study discusses the benefits and drawbacks of globalization in the context of World Trade Organization (WTO) regulations.
The findings indicate that globalization has intensified financial flows between countries, which can exacerbate economic crises. Countries with abundant human resources can capitalize on the international division of labor to specialize in high-value sectors, while those with limited resources risk falling behind in the digital landscape. This division of labor fosters specialization and improves production efficiency through targeted education.
However, multinational corporations often impede cost-effective production in developing nations, underscoring the necessity to restructure research and development to facilitate technology adoption in underdeveloped areas. This restructuring can help close the technological gap and encourage equitable participation in the global economy.

Carbon footprint refers to the total amount of greenhouse gas emitted in the atmosphere by an individual or by an organization causing global warming. There are various causes of greenhouse gas emissions and anaesthetic gases are one amongst them. Greenhouse gases warm the earth by absorbing infrared energy and slowing the rate at which the energy escapes into space. Each greenhouse gas has two important properties. One is the amount of infrared energy that a gas can absorb and the other is the lifetime of that gas in the atmosphere. Anaesthesia as a speciality contributes to carbon footprinting in three ways: direct emission, energy use, and operating room wastes and supplies. Direct emission of Waste Anaesthetic Gases (WAG) from anaesthesia workstations can either be scavenged and thrown out into the environment causing a green greenhouse gas effect or can pollute the operating room due to poor scavenging. Various techniques such as reducing direct emissions, energy use optimisation, and waste management have been tried in minimising carbon footprint in anaesthesia practice but providing safety to the patient is considered of utmost importance.

Previable Preterm Premature Rupture of Membranes (PPROM) before 24 weeks of gestation in dichorionic diamniotic (DCDA) twin pregnancies is a rare and challenging obstetric complication. Three cases are presented in this case series, all involving prolonged latency periods of 74, 98, and 158 days following membrane rupture. The management strategy employed was expectant, utilizing antibiotic prophylaxis and close monitoring to prevent infection. Neonatal outcomes varied, with pulmonary hypoplasia and respiratory distress observed in some cases. One twin from Case 2 died due to sepsis, while the remaining twins in all three instances survived after extended neonatal intensive care. This series highlights the potential for extended latency and favorable outcomes in select cases, though neonatal morbidity remains a significant risk, underscoring the need for individualized counseling and vigilant care.
