Lateral Tarsoplasty Combined with a Full-Thickness Skin Graft for Managing Severe Lower Eyelid Ectropion Following the Subciliary Approach for Infra-Orbital Rim Fracture: A Retrospective Observational Study.

Subciliary incision is a common approach for facial fracture surgery; however, it has a higher incidence of lower lid ectropion, which can be particularly challenging for beginning surgeons to manage. This study reports the usage of lateral tarsoplasty combined with a full-thickness skin graft (FTSG) to correct severe ectropion following the subciliary approach for infra-orbital rim fractures. We retrospectively reviewed all facial fracture cases involving infra-orbital rim fractures through a subciliary approach treated in our department between March 2021 and May 2023.

Comparison of anaerobic digestion of starch- and petro-based bioplastic under hydrogen-rich conditions.

To identify an economically viable waste management system for bioplastics, thermoplastic starch (TPS) and poly(butylene adipate-co-terephthalate) (PBAT) were anaerobically digested under hydrogen (H)/carbon dioxide (CO) and nitrogen (N) gas-purged conditions to compare methane (CH) production and biodegradation. Regardless of the type of bioplastics, CH production was consistently higher with H/CO than with N. The highest amount of CH was produced at 307.

A comparative study on the distribution behavior of microplastics through FT-IR analysis on different land uses in agricultural soils.

Plastic materials have been variously exposed to arable land for decades through soil mulching, plastic housing, and sewage sludge composting. Their mechanical abrasion and biochemical degradation induce the proliferation of myriad microplastics that can further be broken into smaller nano-sized pieces that can be further accumulated in living organisms (including soil invertebrates, fruits, and vegetables); they can also be widely dispersed in neighboring environments. Despite the intensive use of plastics in agriculture, little is known about their origin of occurrence and environmental fate, especially with a size below 100 μm.

Rapid surface degradation of co-axially arranged polypropylene globules by nanoporous carbonized TiO assisted with UV-C.

The degradation of plastics, especially polypropylene (PP), is difficult since it is the most hydrophobic polymer. Photocatalytic degradation of PP films has been reported to be one of the most efficient degradation techniques. However, it is still insignificant to employ it in field applications.

Comparison of the bacterial viability assessments for the disinfected quarantined water along with an effect of total residual oxidants.

This study thus compared the viability of three different pathogenic bacteria (Escherichia coli, Vibrio harveyi, and Enterococcus faecalis) in either seawater or freshwater after their disinfection. For that, they were treated by ozonation (2.

Long-term nationwide assessment of polychlorinated dibenzo-p-dioxins/dibenzofurans and dioxin-like polychlorinated biphenyls ambient air concentrations for ten years in South Korea.

As a result of strict regulation enforced by Korea Ministry of Environment in 2008, PCDD/DFs concentrations in the ambient air decreased from 0.051 pg I-TEQ Sm in 2009 to 0.

A case study on the correlation between radon and multiple geophysicochemical properties of soils in G island, Korea, and effects on the bacterial metabolic behaviors.

This study was conducted to assess the natural radiation intensity of radon observed from 'G' islands and its effects against Bacillus pumilus, predominantly found throughout the field survey.

Reconstruction of infected trunk wounds with pedicled rectus abdominis musculocutaneous flaps: a retrospective case series.

Objective: To completely treat and cover extensively infected trunk defects, reconstruction should be performed using a sufficiently vascularised flap, such as a muscle or musculocutaneous flap after perfect debridement. These reconstructive surgeries are challenging in patients with severe comorbidities. In this case series, we describe extensively infected trunk defect reconstruction, in patients with severe comorbidities, using a pedicled rectus abdominis musculocutaneous flap and suggest an algorithm for reconstruction.

Redox-mediator-free degradation of sulfathiazole and tetracycline using Phanerochaete chrysosporium.

The removal of two of the most commonly used antibiotics, tetracycline (TC) and sulfathiazole (STZ), using laccase-producing Phanerochaete chrysosporium was studied in liquid-phase batch experiments in the absence of any synthetic redox mediator. The removal of STZ and TC from single antibiotic spikes varied from 97.8% to 15.

Quantification of residual antibiotics in cow manure being spread over agricultural land and assessment of their behavioral effects on antibiotic resistant bacteria.

Antibiotic resistant bacteria (ARB) in livestock manure used as fertilizer and spread over agriculture land, may pose a threat to the health of humans. Considering this, the concentrations of tetracycline (TC), oxytetracycline (OTC), and sulfathiazole (STZ) in the surface soil were quantified using LC-MS. These antibiotics have been used in livestock and are found in fertilizer produced from livestock excretions.

Comparative enzyme inhibitive methanol production by Methylosinus sporium from simulated biogas.

Methane in a simulated biogas converting to methanol under aerobic condition was comparatively assessed by inhibiting the activity of methanol dehydrogenase (MDH) of Methylosinus sporium using phosphate, NaCl, NH4Cl or EDTA in their varying concentrations. The highest amount of methane was indistinguishably diverted at the typical conditions regardless of the types of inhibitors: 35°C and pH 7 under a 0.4% (v/v) of biogas, specifically for <40 mM phosphate, 50 mM NaCl, 40 mM NH4Cl or 150 µM EDTA.

Partial oxidative conversion of methane to methanol through selective inhibition of methanol dehydrogenase in methanotrophic consortium from landfill cover soil.

Using a methanotrophic consortium (that includes Methylosinus sporium NCIMB 11126, Methylosinus trichosporium OB3b, and Methylococcus capsulatus Bath) isolated from a landfill site, the potential for partial oxidation of methane into methanol through selective inhibition of methanol dehydrogenase (MDH) over soluble methane monooxygenase (sMMO) with some selected MDH inhibitors at varied concentration range, was evaluated in batch serum bottle and bioreactor experiments. Our result suggests that MDH activity could effectively be inhibited either at 40 mM of phosphate, 100 mM of NaCl, 40 mM of NH4Cl or 50 μM of EDTA with conversion ratios (moles of CH3OH produced per mole CH4 consumed) of 58, 80, 80, and 43 %, respectively. The difference between extent of inhibition in MDH activity and sMMO activity was significantly correlated (n = 6, p < 0.
