Risk Factors of Neonatal Mortality in Bangladesh
SMM Kamal,M Ashrafuzzaman,SA Nasreen
Journal of Nepal Paediatric Society , 2012, DOI: 10.3126/jnps.v32i1.4845
Abstract: Introduction: To address United Nations Millennium Develop-ment Goal 4 (MDG 4) on reducing childhood mortality by three-quarter by 2015, there is a need for better population-based data on the rates and causes of neonatal death. This study aims to identify the risk factors of neonatal mortality in Bangladesh.

African Journal of Biotechnology , 2010,
Abstract: The application of STREAMLINE Direct HST adsorbent in expanded bed adsorption of lipase from Burkholderia pseudomallei was explored in this study. Scouting of optimum binding and elution condition was performed in batch binding mode. The addition of 0.2 M salt in acetate buffer (pH 5) during adsorption has increased the specificity and quantity of lipase binding onto the adsorbent. The addition of 0.4 M salt in phosphate buffer (pH 7) achieved the highest purification fold (2.5) in elution. The high density of the adsorbent allowed the EBA to be operated at linear velocity as high as 657 cm/h with feedstock containing 4.5% (w/v) wet biomass. The Richardson-Zaki correlation obtained for this EBA system at the presence of 4.5% (w/v) wet biomass is 5.14, a value closed to the laminar flow regime of 4.8, demonstrated that a stable bed is achieved under this operating condition. Meanwhile, a flow velocity of 343 cm/h with bed expansion of 3.2 gave highest dynamic binding capacity (4979.28 U/ml) and productivity (61.52 U/ml.min) for this EBA operation. It also demonstrated that biomass concentration up to 4.5% (w/v) wet weight showed slightly drop of sorption efficiency (0.82) compared to lower biomass concentration (0.94). Further increase of biomass concentration above 4.5% (w/v) wet weight has greatly decreased the equilibrium and dynamic capacity. Application of high density adsorbent tolerated to high density and biomass has reduced the processing time and increased the productivity.
Precocious Puberty and Primary Hypothyroidism
A Rabbani,SMM Moezi
Iranian Journal of Pediatrics , 1990,
Abstract: We report a 7-year-old Iranian girl with precocious puberty due to primary hypothyroidism. She is a case of thyroid gland dysgenesis that leads to thyroprivic hypothyroidism with concomitant hyperprolactinemia, elevated gonadotropin level, enlarged uterus, polycystic ovarious and hyperesterogenism with natural breasts and menarche. With thyroid replacement therapy her breasts regressed, ovarian cysts disappeared and serum gonadotropin, prolactin and estrogen levels returned to normal values. We conclude that hypothyroidism is a rare cause of true precocious puberty and the impaired feedback control of hypothalamic pituitary pathway in these patients will be suppressed with thyroxin

Dressing after Dressing: Sadra’s Interpretation of Change  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.31009
Abstract:

This paper deals with the doctrine of transubstantial change advocated by Mulla Sadra in which substances as well as accidents are thought to be in constant and gradual change. Against Aristotle’s doctrine of accidental change, Mulla Sadra argues that no stable ground can bring about change and since substance is renewable it cannot carry identity of a changing existent. Here we investigate whether identity is possible or not. If it is possible then what becomes a ground for establishing identity of changing substances.

Aliskiren Augments the Activities of Anti-Oxidant Enzymes in Liver Homogenates of DOCA Salt-Induced Hypertensive Rats  [PDF]
Sahar Kamal
Advances in Enzyme Research (AER) , 2014, DOI: 10.4236/aer.2014.22010
Abstract: Hypertension is a serious problem that is recently thought to be associated with damaging effects on target organs partially via oxidative stress. On the other hand, there is accumulating literature describing some sort of therapeutic interaction between antioxidant enzymes in vital organs and hypertension. Therefore, the aim of this study is to investigate the possible effect of a direct renin inhibitor, aliskiren, used in treatment of hypertension via renin-angiotensin-aldosterone system (RAAS), on selected anti-oxidant enzymes in hepatic homogenates in DOCA salt-induced hypertesnive albino rats. Thirty male wister albino rats were assigned randomly into 3 groups (n = 10/ group). Group 1 received no treatement and serves as control. Group 2 received 0.5% carboxymethylcellulose sodium ip as a solvent of aliskiren, as a direct renin inhibitor (DRI). Group 3 received aliskiren 100 mg/kg/day ip for 4 weeks through gastric tube. Systolic blood pressure (SBP) was measured every week and its mean was recorded at the end of the study. Superoxide dismutase (SOD) enzyme in RBCs lysates, activities of catalase (CAT) and glutathione peroxidase enzymes and thiobarbituric acid reactive substance (TBARS), as a marker of lipid peroxidation, in hepatic homogenates were measured at the end of the study. DRI produced a marked reduction in mean SBP of hypertensive rats. It also significantly (p < 0.05) increased the activities of measured anti-oxidant enzymes while it significantly (p < 0.05) reduced TBARS in liver homogenates. These results indicated that renin possesses an oxidative effect in the liver in hypertensive rats. Aliskiren, in addition to its powerful anti-hypertensive effect, it could induce a great anti-oxidant effect in liver homogenates of DOCA salt-hypertensive rats.
Individual Essences in Avicenna’s Metaphysics  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.41004
Abstract:

Central to Aristotle’s metaphysics is the question of individuality. The individuality of each substance is explained in relation to matter because the form is universal. Avicenna, as one of the Aristotelian Neoplatonist philosophers, is not content with this explanation and proposes to establish individuality on other grounds. In this paper, I argue that in his perspective it is not the matter which determines individuality but rather the principle of existence.

 

Metal-Like Gravity and Its Cosmological Applications  [PDF]
Kamal Barghout
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.518211
Abstract: Modification to Newton gravitational interaction is presented. It provides an understanding of a novel universal gravitational field of particle origin that defines alternative attributes to elementary constituents of matter particles and the gravitational interactions between them. It investigates gravitational relationship between two types of mass. The model assigns Coulombic gravitational interaction to DM particles and baryons by attributing self-antigravity to both normal matter and dark matter (DM). It defines the interaction as like particles repel while unlike particles attract. Metal-like force is proposed where same type mass (baryons) are gravitationally attracted to each other when a sea of DM particles are attracted to them and glue them together analogous to a metal bond. At close range, other dominant forces take place such as electromagnetic force. In light of this model, intergalactic self-repulsive DM particles are proposed to result in accelerating expansion of the universe. The model produces flat rotational curves for spiral galaxies and provides a physical explanation to MOND theory.
MLG vs. MOND  [PDF]
Kamal Barghout
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.64053
Abstract: In a recently published paper Metal-Like Gravity (MLG) and Its Cosmological Applications [1], it was determined that a new modification of Newtonian gravity could explain many of the cosmological mysteries such as the nature of dark matter and dark energy. The theory provided a gravitational physical system and explained the flatness of the galactic rotational curves (RC). A RC fit that was identical to MOND’s RC fit for spiral galaxies was generated with α as a fitting parameter determined as equal to 1.345. In this paper I am elaborating more on the theory’s cosmological extrapolation of MOND’s critical acceleration a0. This is done by further assessing the gravitational interaction between the galactic baryonic mass and the halo-DM mass in the star-galaxy overlapping volume estimated in MLG framework interpreting a0 as only a factor induced from the reduction of the galactic luminous mass. It is asserted that MOND and MLG dynamic equations are equivalent with MOND’s form, only expressing the equation with an intermediate solution by equating the magnitudes of δ (a parameter that defines a scaled surface galactic DM-density perpendicular to the galactic radial direction in the galaxy-star halo overlapping volume) and G.
Avicenna’s Necessary Being  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2016, DOI: 10.4236/ojpp.2016.62018
Abstract: This article examines the distinctive characteristics of Avicenna’s doctrine of the Necessary Being, arguing that Avicenna developed his doctrine under the influence of Aristotle’s metaphysical thinking, but, unlike Aristotle he does not proceed from the distinction between form and matter. Instead, Avicenna has established his doctrine on essence-existence dichotomy. The article also investigates Avicenna’s view on God’s knowledge of particulars in light of his doctrine of the Necessary Being. The article begins by discussing Aristotle’s analysis of the meaning of the prime cause and its simplicity. It will then examine the simplicity of the Necessary Being in light of Aristotle’s metaphysics.
