    Understanding altered intrinsic heart rate in type 2 diabetes

    Heart rate (HR) is generated by sinoatrial node (SAN) intrinsic pacemaking and modulated by autonomic innervation. Within the SAN, intrinsic (ex vivo) HR is determined by the mutual entrainment of the sarcolemmal voltage membrane (Vm) and intracellular Ca2+ clocks. The Vm clock involves membrane ion channels, such as the hyperpolarisation-activated cyclic nucleotide-gated channel 4 (HCN4), transient type (T-type) and long-lasting type (L-type) Ca2+ channels and the ion transporter Na+-Ca2+ exchanger 1 (NCX1). The Ca2+ clock primarily involves the intracellular Ca2+ store, the sarcoplasmic reticulum (SR), and the Ca2+ release protein the ryanodine receptor 2 (RyR2), the Ca2+ uptake protein the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA2a) and its regulator phospholamban. Conduction of the AP within the SAN occurs via the coupling protein connexin 45 (cx45). Additionally, the presence of the non-neuronal cardiac intrinsic cholinergic system within cardiomyocytes suggests it might also be present in the SAN cardiomyocytes and have the capacity to modulate intrinsic HR. Disruption of HR control occurs in patients and animal models with type 2 diabetes (DM). Interestingly, in the DM Zucker Diabetic Fatty (ZDF) rats, intrinsic HR was significantly decreased compared to non-diabetic (nDM) controls. This suggests DM impairs the intrinsic ability of the SAN to generate a normal HR. Therefore, the overall aim of this research was to investigate whether the decreased intrinsic HR in DM was due to changes in the Vm and / or Ca2+ clocks, cx45 and / or increased non-neuronal intrinsic cholinergic system activity. The SAN / hearts of 19 – 22 week-old nDM and DM ZDF rats were used to investigate protein expression of the key SAN clock, cx45 and cholinergic proteins via western blotting, intrinsic HR contributions from HCN4, SERCA2a and muscarinic type 2 (M2) receptor via Langendorff, and SAN cellular / tissue morphology via immunohistochemistry. For the Vm clock, a significant increase in HCN4 (nDM 0.83 ± 0.07 versus DM 1.67 ± 0.19, p0.05) or SERCA2a to phospholamban ratio (nDM 2.97 ± 0.68 versus DM 2.37 ± 0.34, p>0.05) was found in DM. A significant increase in the M2 receptor expression (nDM 1.14 ± 0.18 versus DM 3.14 ± 0.80, p0.05). For immunohistochemistry, no difference in cellular / tissue distribution of key SAN clock, cx45 or cholinergic proteins was observed, or in the levels of fibrosis (p>0.05) and fat (p>0.05) within the DM SAN. Collectively, this study presents novel mechanisms that are altered in pacemaking in the type 2 DM SAN. From this research, I conclude, the lower intrinsic HR in DM is, in part, a result of changes to both the Vm and Ca2+ clock due to non-functional HCN4 channels and compromised SERCA2a activity that would prolong diastolic depolarisation and repolarisation respectively

    This paper investigates the factors behind the runaway women and the untapped phenomenon of family structures where such incidents are reported. We used broader concept of women empowerment to explore the runaway causes through the provision of living, wage jobs, education, medical and health facilities in targeted population. The respondents are selected from the shelter homes of Punjab province in Pakistan where data are collected through in-depth interviews from the Runaway women and the management of different shelter homes. The transformation of data is conducted through thematic analysis. Our result indicates that domestic violence, physical & sexual abuses, life threats, and forced marriages are the reasons behind women’s runaway. The shelter homes’ management added that illiteracy and perceived destructive role of media are the additional causes in runaway incidents. Our results provide important insights on backdrop of women runaways in developing societies. Accordingly, there is an immediate need for the government and social policy agencies to take cohesive measures to support socially affected women at their door step in order to minimize such social violence.Este artículo investiga los factores detrás de las mujeres fugitivas y el fenómeno sin explotar de las estructuras familiares donde se informan tales incidentes. Utilizamos un concepto más amplio de empoderamiento de las mujeres para explorar las causas fugitivas a través de la provisión de vida, empleos asalariados, educación, servicios médicos y de salud en la población destinataria. Los encuestados son seleccionados de los hogares de acogida de la provincia de Punjab en Pakistán, donde se recopilan datos a través de entrevistas en profundidad de las mujeres fugitivas y la gestión de diferentes hogares de refugio. La transformación de los datos se realiza mediante análisis temático. Nuestro resultado indica que la violencia doméstica, los abusos físicos y sexuales, las amenazas a la vida y los matrimonios forzados son las razones del fugitivo de las mujeres. La administración de las casas de acogida agregó que el analfabetismo y el papel destructivo percibido de los medios son las causas adicionales de los incidentes fugitivos. Nuestros resultados proporcionan información importante sobre el contexto de las mujeres fugitivas en las sociedades en desarrollo. En consecuencia, existe una necesidad inmediata de que el gobierno y las agencias de política social tomen medidas cohesivas para apoyar a las mujeres socialmente afectadas en su puerta para minimizar dicha violencia social

    This study has two-fold purposes; first is to explore the partner violence on housemaids and second is their economic exploitation by their partner and at the workplace. Through analysis of interviews of the housemaid, it is explored that unemployment, drug addiction, ignorance of basic rights, poverty, illiteracy, financial crises are the main reasons of physical, psychological and sexual violence by the partner on housemaids. The economic exploitation of housemaids is due to the male-dominated society, gender discrimination and not predefined policy and rules about the wage rate in Pakistan. There is a need to per hour wage rate, proper reporting system against violence and empowerment of women in the society for the protection of their rights.Este estudio tiene dos propósitos; primero es explorar la violencia de la pareja en las empleadas domésticas y segundo es su explotación económica por parte de su pareja y en el lugar de trabajo. A través del análisis de entrevistas a la criada, se explora que el desempleo, la drogadicción, la ignorancia de los derechos básicos, la pobreza, el analfabetismo, las crisis financieras son las principales razones de violencia física, psicológica y sexual por parte de la pareja en las criadas. La explotación económica de las empleadas domésticas se debe a la sociedad dominada por los hombres, la discriminación de género y las políticas y normas no predefinidas sobre la tasa salarial en Pakistán. Existe la necesidad de una tasa salarial por hora, un sistema de denuncia adecuado contra la violencia y el empoderamiento de las mujeres en la sociedad para la protección de sus derechos
