This work provides a new, low-cost, and effective route to improve the performance of TiO2 for effective removing TPMs.Soil phosphorus fractions in wetland ecosystems have received increasing attention due to its high eutrophication risks. Soil samples were collected to 40 cm depth in three sampling seasons to investigate the seasonal dynamics of organic and inorganic phosphorus fractions, bioavailability, and relationship between those and soil properties in a seasonal-flooding wetland in the Yellow River Estuary. The results showed that inorganic phosphorus (IP) and organic phosphorus (OP) contents exhibited much higher levels in the top 10 cm soils, and declined along soil profiles in spring. IP kept constant along soil profiles in fall, while OP decreased in summer and fall. They were greatly affected by water content (WC), pH, Cl-/SO42-, soil organic matter (SOM), and electrical conductivity (EC). read more Middle labile organic phosphorus (MLOP) and non-labile organic phosphorus (NLOP) accounted for higher percentages of total OP in summer and fall respectively than labile organic phosphorus (LOP) in spring. MLOP and NLOP levels Sustainable desalination can be achieved by adopting renewable energy-based low-cost and low-impact desalting techniques. In this investigation, capability of inclined felt sheet solar distiller in desalting seawater is assessed by evaluating its performance, distillate water quality, economics, and environmental impacts. The distiller with 1.18-m2 aperture area produced around 4.60 L/day of distillate for a cumulative incident solar radiation intensity of about 20.52 MJ/m2 day. Its pollutant removal efficiency is very much superior to other available solar stills reported in literatures. Thermal model developed for estimating distiller's performance is able to predict its productivity with reasonable accuracy (only 8.0% deviation from experimental values) and was used for estimating distiller's performance in various seashore locations in India with varying clear days (191 to 246). Yearly mean distillate production and thermal and exergy efficiencies of the proposed distiller range between 3.60 to 4.50 L/day, 36.45 to 42.39%, and 2.85 to 3.65%, respectively, in east seashore locations of India. Moreover, 18.46 tons of CO2, 132.72 kg of SO2, and 54.20 kg of NO emission can be mitigated by adopting the distiller for potable water production. Distillate production cost of inclined felt sheet solar distiller is in the range of 1.15 to 2.29 INR/L and highly depends on the interest rate at which the distiller is financed. Generation of reasonable quantity of high-quality potable water at low cost with huge environmental benefits makes proposed inclined felt sheet solar distiller a suitable option for quenching thirst in coastal and remote locations.The correct presentation of Table 3 is presented in this paper.The present study assesses the treatability of a real industrial wastewater (WW) with a high organic load (chemical oxygen demand (COD) above 5800 mgO2 L-1) by photo-Fenton's oxidation with the goal of improving the organic matter degradation reached previously, in another work, where the Fenton process was applied in a bubbling reactor. Thus, the process was carried out in a bubble photo reactor (BPR) wherein continuous air supply ensures an efficient mixing of the liquid phase. The effect of the main operatory parameters that influence the WW treatment (i.e., H2O2 and Fe2+ concentrations, initial pH, and UV-Vis radiation intensity) were evaluated, being found that in the best conditions tested (pH0 = 4.6, [Fe2+] = 0.1 g L-1, [H2O2] = 18 g L-1, Qair = 1.0 L min-1-measured at room temperature and atmospheric pressure-and irradiance of 500 W m-2), removals of 95% and 97% for total organic carbon (TOC) and COD, respectively, were achieved. Still, a high reduction of the concentration of the main constituents of this WW was reached, being total for aniline and 86% for sulfanilic acid. The continuous air supply reactor configuration was compared with magnetic stirring; similar mineralization was achieved. However, the air bubbling promotes a good heat transfer within the reactor, minimizing temperature gradients, which is quite advantageous due to the strong exothermicity of the oxidation process during the treatment of such highly loaded real effluents.The current study was conducted to assess the hematological and histopathological changes in major carp (Catla catla) exposed to different concentrations of copper (Cu) and cadmium (Cd). For this purpose, Catla catla fish, weighing approximately 230-235 g, were randomly divided into four groups and then exposed to acute doses of Cu (1.25 ppm), Cd (4.5 ppm), and their mixture (2.25 ppm) for 96 h and then 20, 30, and 40% respectively for a period of 30 days. Results showed that red blood cells (RBCs), hemoglobin (Hb), hematocrit (Hct), lymphocyte, and monocyte decreased significantly, while the total white blood cell count and neutrophil population significantly increased in experimental groups as compared with the control one. Histopathological examination of liver tissues showed karyorrhexis, hepatic cells degeneration, congestion, and hemorrhages. Microscopic analysis of gills' sections revealed lamellar atrophy, telangiectasia, and necrosis of lamellar epithelial cells. In the kidneys, different histopathological ailments like atrophy of glomeruli, necrosis of renal tubular cells, increased urinary spaces, degeneration of renal tubules, and melanomacrophage aggregates were observed, while in the intestine, atrophy of villi, sloughing of epithelial villi, and congestion were seen after 30 days of exposure. In conclusion, the study indicates that exposure to Cu and Cd for longer period of time causes adverse hematological and histopathological changes in Catla catla fish.
A new species of the genus Caligus is described based on specimens collected from pompano, Trachinotus ovatus (Linnaeus), caught in eastern Atlantic waters, near the Madeira archipelago.
Pompano (n = 21) were purchased from the local fish market and examined for parasitic copepods. Morphological features of the copepods were examined and drawn using an Olympus BX51 equipped with a drawing tube. Key diagnostic characters were scanned using a confocal laser scanning microscope and a scanning electron microscope.
Caligus madeirensis sp. nov., can be distinguished from all congeners (270 spp.) by the combination of the following characters (i) an accessory process on the 3 outer terminal spines located on the distal exopodal segment of leg 1, (ii) a mandible with 14 teeth, (iii) a sternal furca with parallel, spatulate tines, (iv) a maxilliped with 2 simple setae at base of a claw, (v) a leg 3 with second endopodal segment with 5 pinnate setae, (vi) a 2-segmented leg 4 exopod with I; III spine formula, (viihe result of which, however, might be due to limited sampling.
In female genital rejuvenation and beautification, interest and demand for combined surgical and non-surgical methods are increasing. This study presents the results of our labia minora reduction technique and a vulvovaginal rejuvenation and beautification concept, where a combination of fat injection into the mons pubis and labia majora, if necessary, combined with fractional carbon dioxide (CO
) laser is used.
Genital rejuvenation and beautification were performed on 37 patients between January 2014 and January 2019. Postoperative follow-up for 1year to obtain data on the satisfaction of surgical and non-surgical procedures was performed.
Of the 37 female patients included in the study, 33 (94.5%) were satisfied or very satisfied with their postoperative appearance. Thirty (80%) patients were satisfied or very satisfied with functional results.
The described genital beautification and rejuvenation technique combines different aesthetic female genital surgery techniques and non-surgical noninvasive procedures. These procedures, like other plastic surgeries and procedures, are designed for the subjective improvement of the patients' appearance and feelings.

Anatomical characteristics that are incongruent with an individual's gender identity can cause significant gender dysphoria. Hands exhibit prominent dimorphic sexual features, but despite their visibility, there are limited studies examining gender affirming procedures for the hands. This review is intended to cover the anatomical features that define masculine and feminine hands, the surgical and non-surgical approaches for feminization and masculinization of the hand, and to adapt established aesthetic hand techniques for gender affirming care.
The authors performed a comprehensive database search of PubMed, Embase OVID and SCOPUS to identify articles on the characterization of masculine or feminine hands, hand treatments related to gender affirmation, and articles related to techniques for hand masculinization and feminization in the non-transgender population.
From 656 possibly relevant articles, 42 met the inclusion criteria for the current literature search. There is currently no medical literaturl description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266. .
For revision surgeries due to complications associated with alloplastic materials, autologous tissues including dermofat are considered. However, graft absorption, shaping, and donor site morbidity remain crucial challenges. This study aimed to present several surgical techniques of dermofat grafting for rhinoplasty to overcome these challenges.
Patients who underwent autologous dermofat grafting from January 2015 to October 2019 were retrospectively studied, and those who underwent primary rhinoplasty were excluded. The mid-sacral dermis (with the thickest dermal layer) was selected as the main donor site. During dermal harvesting, fat was resected into a wedge shape, to minimize flap tension and dead space risk. A molding technique was applied to improve graft shape and height and minimize graft absorption. Patient records were reviewed for assessing preoperative evaluations, surgical methods, and complications. For evaluating aesthetic outcomes, three rhinoplasty surgeons, blinded to the study purpose, compared preoperative and postoperative photographs.
Among 331 cases undergoing dermofat grafting for revision rhinoplasty, 25 underwent revisions; of these, five, one, and nine cases experienced over-absorption, over-correction, and deviation, respectively. One and eight cases underwent revision due to a widening scar at the dermofat donor site and wound dehiscence, respectively. Notably, one case had inflamed sinus formation.
The advanced dermofat graft technique provided favorable results with selection of appropriate donor site and a dermofat graft with subdermal fat. The application of this molding technique and proper management of donor site ameliorated critical disadvantages, thereby providing a safe and effective alternative for revision rhinoplasty.
