To determine whether pain has psycho-social associations in adult Crohn’s disease (CD) *** completed demographics, disease status, Patient Harvey-Bradshaw Index (P-HBI), Short Form Health Survey (SF-36), Short Inflammatory Bowel Disease Questionnaire (SIBDQ), and five socio-psychological questionnaires: Brief Symptom Inventory, Brief COPE Inventory, Family Assessment Device, Satisfaction with Life Scale, and Work Productivity and Activity Impairment Questionnaire. Pain sub-scales in P-HBI, SF-36 and SIBDQ measures were recoded into 4 identical scores for univariate and multinomial logistic regression analysis of associations with psycho-social *** cohort comprised 594 patients, mean age 38.6 ± 14.8 years, women 52.5%, P-HBI 5.76 ± 5.15. P-HBI, SF-36 and SIBDQ broadly agreed in their assessment of pain intensity. More severe pain was significantly associated with female gender, low socio-economic status, unemployment, Israeli birth and smoking. Higher pain scores correlated positively with psychological stress, dysfunctional coping strategies, poor family relationships, absenteeism, presenteeism, productivity loss and activity impairment and all WPAI sub-scores. Patients exhibiting greater satisfaction with life had less pain. The regression showed increasing odds ratios for psychological stress (lowest 2.26, highest 12.17) and female gender (highest 3.19) with increasing pain. Internet-recruited patients were sicker and differed from hardcopy questionnaire patients in their associations with *** measures in P-HBI, SF-36 and SIBDQ correlate with psycho-social pathology in CD. Physicians should be aware also of these relationships in approaching CD patients with pain.

Orbital fractures are a frequent and serious problem for practicing ophthalmologists. The complexity of the pathology is explained by the combined nature of the injuries(often associated with craniofacial injuries), multistage treatments, results that are often unsatisfactory, and a wide range of complaints about functional and cosmetic limitations. Over the years, significant progress has been made in the field of orbital reconstruction,allowing the transition from traditional methods using simple materials to innovative bioengineering *** evolution has been driven by advances in surgical technologies, imaging techniques, and biomaterials aimed at optimizing the restoration of the shape and function of the orbital region. Traditional approaches are based on the use of autologous tissues such as bone grafts and muscle flaps, which provide biocompatibility and natural integration, but have limitations in terms of customization and accessibility. The advent of patient-specific implants and 3D printing technology has revolutionized the reconstruction of the orbit, allowing implants to be precisely adapted to a patient's anatomy. Biocompatible materials, such as porous polyethylene, titanium, and silicone, have become the basis for orbital reconstruction, ensuring durability and compatibility while minimizing long-term complications. Bioengineered solutions hold promise for further advancements in orbital reconstruction. We searched Pub Med, Cyberleninka, and other verified databases for published articles on orbital reconstruction reported in the literature between 1960 and January 2024. In this article, we consider the advantages and disadvantages of each category of reconstruction materials and provide up-to-date information on the methods for modifying their properties using modern processing technologies.

Nitrite pre-treatment of dewatered sludge for microbial fuel cell application

引用

Journal of Environmental Sciences 2019年第3期31卷 148-155页

作者： Abdul Rasyid ruslan Vel Murugan Vadivelu School of Chemical Engineering Universiti Sains MalaysiaEngineering Campus

The effect of pre-treatment of dewatered sludge using different nitrite concentrations and p H for microbial fuel cell(MFC) application was investigated. The results show that the addition of nitrite was feasible to increase the solubilization rate of the sludge and may reduce mass transfer limitation at the anode. This helped the MFC to reach higher voltage and to generate more power. The higher free nitrous acid(FNA) concentration under the acidic condition helped to increase sludge solubilization. However, under an alkaline condition, during which the FNA concentration was relatively low, the solubilization of the sludge was higher. The highest voltage and power density produced was 390 mV and 153 mW/m^2, respectively, with the addition of nitrite at 100 mg-N/L and pH 9. Furthermore,it was found that elevated levels of FNA could inhibit electrogenic bacteria thus reducing power generation.

Archaeological Mineralogy and the Dawn of Gemmology:Prehistoric(7th-5th Millennium BC)Gem Minerals and Gold from the Balkans（South-East Europe）

引用

宝石和宝石学杂志 2019年第4期21卷 25-35页

作者： ruslan I.Kostov University of Mining and Geology "St.Ivan Rilski"

The territory of the Balkan Peninsula in SE Europe is reviewed, from the point of gemmology, as the cradle of gem and decorative minerals and metals in European prehistory. During the local Neolithic period (end of 7 th -6 th millennium BC), as material for tools or for beads, nephrite (with the earliest known Balkan nephrite culture), jadeite-omphacite and quartz (different varieties) were introduced to make pendants and idols. Large quantities of copper and gold artifacts are known since the Chalcolithic period (5 th millennium BC)(unique for the region;the largest in number of gold artifacts is the Varna I Chalcolithic necropolis in Bulgaria). The gemmological materials in the Balkans are known for malachite, antigorite serpentinite, turquoise, rock crystal, carnelian, jasper, jet and obsidian. In the Varna I necropolis (mid 5 th millennium BC) are recorded the first known complex faceted carnelian beads with 32 facets, as well as some of the most important gemmological techniques and procedures such as faceting, tumbling, annealing, miniaturization and standardization. As pigments for pottery, cinnabar, graphite and gold were used in different prehistoric sites. The earliest salt production in the Balkans is known from sites in Romania and Bulgaria, and because of its trade, salt is positively linked to a population rich with prestigious goods. The introduced possible Chalcolithic weight unit “van”(2 carats) is supposed to be the earliest known in prehistoric times.

Tribological study on the surface modification of metal-on-polymer bioimplants

Frontiers of Mechanical Engineering 2022年第2期17卷 103-115页

The tribological performance of artificial joints is regarded as the main factor of the lifespan of implanted prostheses. The relationship between surface roughness and coefficient of friction (COF) under dry and lubricated conditions is studied. Results show that under dry test, friction coefficient is not reduced all the time with a decrease in surface roughness. On the contrary, a threshold of roughness value is observed, and frictional force increases again below this value. This critical value lies between 40 and 100 nm in Sa (roughness). This phenomenon is due to the transfer of friction mechanisms from abrasion to adhesion. Under wet test, COF always decreases with reduction in surface roughness. This result is mainly attributed to the existence of a thin layer of lubricant film that prevents the intimate contact of two articulating surfaces, thus greatly alleviating adhesion friction. Furthermore, surface texturing technology is successful in improving the corresponding tribological performance by decreasing friction force and mitigating surface deterioration. The even-distribution mode of texturing patterns is most suitable for artificial joints. By obtaining the optimal surface roughness and applying texturing technology, the tribological performance of polymer-based bioimplants can be greatly enhanced.

With the developments in medical technology and increased surgical experience, advanced laparoscopic surgical procedures are performed successfully. Laparoscopic abdominal surgery is one of the best examples of advanced laparoscopic surgery (LS). Today, laparoscopic abdominal surgery in general surgery clinics is the basis of all abdominal surgical interventions. Laparoscopic abdominal surgery is associated with systemic and splanchnic hemodynamic alterations. Inadequate splanchnic perfusion in critically ill patients is associated with increased morbidity and mortality. The underlying pathophysiological mechanisms are still not well understood. With experience and with an increase in the number and diversity of the resulting data, the pathophysiology of laparoscopic abdominal surgery is now better understood. The normal physiology and pathophysiology of local and systemic effects of laparoscopic abdominal surgery is extremely important for safe and effective LS. Future research projects should focus on the interplay between the physiological regulatory mechanisms in the splanchnic circulation (SC), organs, and diseases. In this review, we discuss the effects of laparoscopic abdominal surgery on the SC.
