Open Journal of Ophthalmology 2024年第3期14卷 229-235页

作者： Aïssatou Aw Soda Mbaye Jean Pierre Diagne Sy El Hadji Malick Alassane ba Aly Mbara ka Serigne Sohibou Gaye Ousmane Ndiaga Senghor Lamine Ndiaye Mouhamed Ndiaye El Hadj Abdellahi Seyid papa Amadou Ndiaye Ophthalmology Department of Abass NDAO Hospital Cheikh Anta Diop University Dakar Senegal

Purpose: To show epidemiological and imaging aspects of congenital optic disc abnormalities diagnosed late. Method: It was a retrospective study, including all patients with congenital optic disc abnormalities diagnosed at a late age between January 2020 and October 2022 at the eye center of Abass Ndao Hospital. Complete ophthalmological examination was performed with eye imaging according to the cases. Results: 09 patients (10 eyes) were diagnosed with congenital optic disc abnormalities. The mean age was 29 years, with a sex ratio of 0.8. Three patients had consulted for unilateral decreased visual acuity since childhood, two for sudden vision loss and in four cases the diagnosis was fortuitous. Visual acuity was ranged from 1/200 to 20/20. Fundus examination showed myelinated retinal nerve fibers in four eyes, optic disc pit in three eyes including two complicated by maculopathy, two cases of morning glory syndrome and a case of pseudoduplication of the optic disc. Optical coherence tomography, ocular ultrasound B and OCT-Angiography were performed according to the cases. Conclusion: Congenital optic disc abnormalities are often diagnosed late. They are potentially amblyogenic and complications are not rare, worsening the visual prognosis. Their screening should be systematic by ophthalmological examination in newborns.

Microstructure and Property Relationships in Resistance Spot Weld between 7114 Interstitial Free Steel and 304 Austenitic Stainless Steel

引用

Journal of Materials Science & Technology 2006年第3期22卷 375-381页

作者： Ahmet Hasanba■o■lu Ramazan kaar Department of Metal Education karabük Technical Education Faculty Karabük 78100 Turkey

Due to the differences in physical, chemical and mechanical properties of the base metals, the resistance spot welding of dissimilar materials is generally more challenging than that of similar materials. The influence of the primary welding parameters affecting the heat input such as peak current on the morphology, microhardness, and tensile shear load bearing capacity of dissimilar welds between 304 grades austenitic and 7114 grade interstitial free steel has been investigated in this study. The optimum welding parameters producing maximum joint strength were established at a peak current of 9 ka, where the electrode force is kept 6×10^-5 pa and weld time is kept constant 17 cycles, respectively. The primary cause of weakening the weldment is identified as the excessive grain growing region of heat affected zone （HAZ） in case of 7114 grade interstitial free steel.

Intracellular organelle networks： Understanding their organization and communication through systems-level modeling and analysis

引用

Frontiers in Biology 2017年第1期12卷 7-18页

作者： Qinle ba Ge Yang Department of Biomedical Engineering Carnegie Mellon University Pittsburgh PA 15213 USA Department of Computational Biology Carnegie Mellon University Pittsburgh PA 15213 USA

baCKGROUND： Membrane-bound intracellular organelles are biochemically distinct compartments used by eukaryotic cells for serving specialized physiological functions and organizing their internal environment. Recent studies revealed surprisingly extensive communication between these organelles and highlighted the network nature of their organization and communication. Since organization and communication of the organelles are carried out at the systems level through their networks, systems-level studies are essential for understanding the underlying mechanisms. METHODS： We reviewed recent studies that used systems-level quantitative modeling and analysis to understand organization and communication of intracellular organelle networks. RESULTS： We first review modeling and analysis studies on how fusion/fission and degradation/biogenesis, two essential and closely related classes of activities of individual organelles, collectively mediate the dynamic organization of their networks. We then turn to another important aspect of the dynamic organization of the organelle networks, namely how organelles are physically connected within their networks, a property referred to as the topology of the networks in mathematics, and summarize some of their distinct properties. Lastly, we briefly review modeling and analysis studies that aim to understand communication between different organelle networks, focusing on cellular calcium homeostasis as an example. We conclude with a brief discussion of future directions for research in this area. CONCLUSIONS： Together, the reviewed studies provide critical insights into how diverse activities of individual organelles collectively mediate the organization and communication of their networks. They demonstrate the essential role of systems- level modeling and analysis in understanding complex behavior of such networks.

An odyssey through Fitz-Hugh Curtis syndrome

Journal of Reproduction and Contraception 2015年第3期26卷 173-186页

Acute fibrinous perihepatitis due to genital tract infection has attracted sparse and fluctuating interest. The recent increase in the incidence of sexually transmitted disease and the recognition of Chlamydia trachomatis as a causative organism in both pelvic inflammatory disease （PID） and extra pelvic manifestation of PID have brought about the renewed interest in perihepatitis. This is likely to ensure that the clinical features of perihepatitis will now become widely recognised. This paper examines the evolution, clinical features, diagnosis and management of this interesting syndrome and emphasises the need to explore the upper abdomen during laparoscopic gynaecological surgery.

Evaluation of Current Termination of Pregnancy and Related Services at Grimsby(UK) and Recommendations for Service Improvement

引用

Journal of Reproduction and Contraception 2013年第3期24卷 181-193页

作者： ka Yan Shirley SZE Ibrahim BOLAJI Department of Obstetrics and Gynaecology Hull York Medical School(HYMS)DianaPrincess of Wales HospitalScartho RoadNLAG NHS Foundation TrustGrimsby DN33 2BAEngland

Objective To develop local termination of pregnancy （TOP） dataset and to identify ＂hotspots＂ for highest activity and gaps in our fertility control services. Methods This was a retrospective analysis of 305 women who received TOP under section C of the Abortion Act 1967 over a period of 9 consecutive months from 1st March through to 31st October 2012. Results There were 275 （90.2%） British White （BW） and 30 non-BW women. Among 30 non-BW women, 10 （3.3%） were British Asian, 8 （2.6%） were Polish, 6 （2.0%） were British Black or Black, 5 （1.6%） were Chinese and i （0.3%） was White Latvian. The TOP rate was 8.9% in the under 18 years old and 27.9% in the over 30 years old. Totally 240 TOPs （78. 7%） occurred in 〈10 weeks and 276 TOPs （90.5%） occurred under 13 weeks of gestation. Eight-five women who received TOP-service have had one or more previous termination（s） in the last 3 years. The contraception use was low pre-TOP and none of the women were on long-acting reversible contraception （LARCs） pre- TOP, including those who had repeat terminations. Conclusion There are inequalities and gaps in the TOP and related services in Grimsby which must be addressed to reduce the rate of TOP. This is a major challenge involving multiple agencies. Provision of contraception across all age and ethnic groups, improving sex education, engaging with parents and women to improve their negotiation skills for safer sex, supporting vulnerable women, reducing risk factors e.g. alcohol and substance misuse and raising aspirations across the region will contribute to a reduction in termination rate.
