er when evaluating and designing biomaterials. Through incorporation of basic biological research alongside engineering research, we provide an important lens through which to evaluate adaptive immune contributions to regenerative medicine and medical device development.Electrohydrodynamic Jet 3D Printing (e-jetting) is a promising technique developed from electrospinning, which enables precise fiber deposition in a layer-by-layer fashion with customized designs. Several studies have verified that e-jetted scaffolds were able to support cell attachment, proliferation, and extracellular matrix formation, as well as cell infiltration into the scaffold due to the well-defined pores. Besides, e-jetting has also been combined with other techniques to incorporate biomaterials (e.g., hydrogels and cell spheroids) that could not be e-jetted, to promote the biological performance of the scaffold. In the recent decade, applying e-jetting in the fabrication of tissue-engineered scaffolds has drawn a lot of interest. Moreover, efforts have been put to develop varied scaffolds for some specific biomedical applications such as cartilage, tendon, and blood vessel, which exhibited superior mechanical properties and promoted cell behaviors including cellular alignment and differentiation. Th There is no doubt that e-jetting will be a great tool for tissue engineered scaffolding, and this review article will give overall perspectives in this topic.
Studies have reported that prenatal exposure to fine particulate matter (PM
) might be associated with adverse birth outcomes in offspring. However, evidence with regard to the effects of prenatal exposure to PM
and, especially, its main chemical constituents on offspring's weight in childhood is limited and inconsistent.

The present study aimed to examine associations of prenatal exposure to PM
total mass and its chemical constituents in each trimester with children's weight from birth to 6years of age using data from Shanghai-Minhang Birth Cohort Study.

A total of 1,084 mother-infant pairs were included with both PM
exposure data and at least one measurement of weight and height. Weight-for-Length (WLZ), BMI-for-Age (BMIz), and Weight-for-Age (WAZ) z-scores were generated according to the World Health Organization guidelines. Exposure to PM
total mass and its chemical constituents [organic carbon (OC), black carbon (BC), ammonium (NH

), nitrate (NO

), sulfate (SO

), and soil dust (SOat 6years of age in girls. Our findings suggest that prenatal exposure to PM
and its chemical constituents may have a lasting effect on offspring's weight in childhood.
Prenatal exposure to PM2.5 total mass and its main chemical constituents was associated with decreased weight in boys from 1 to 6 years of age, with increased weight at birth and decreased weight at 6 years of age in girls. ABT-199 purchase Our findings suggest that prenatal exposure to PM2.5 and its chemical constituents may have a lasting effect on offspring's weight in childhood.Sport climbing is increasingly popular and consultations by climbers in hand surgery departments are on the increase. The pathologies related to this sport concern essentially the pulley system, tendons being rarely affected. We report the case of a male climber who presented an atypical rupture of the flexor superficialis tendon in his left middle finger sustained when using an atypical climbing grip technique the "hook grip". This consists in extension of the metacarpophalangeal joints and maximal flexion of the proximal interphalangeal joints with force exerted only on middle phalanx of the middle finger. A biomechanical analysis using finger musculoskeletal modeling was performed to compare the hook grip to other grips, and the patient's recovery performance was assessed. Adapted functional treatment with physiotherapy seems to have been a good option for the treatment of this atypical lesion since the patient recovered normal use of his finger in daily life. He recovered maximal force in climbing holds. The biomechanical analysis confirmed that the atypical "hook grip" was likely at the origin of the rupture, since flexor digitorum superficialis tendon force for this grip is greater than in other climbing grip techniques. The "hook grip" seems to be dangerous and should be used cautiously by climbers to prevent similar pathology. Additionally, the patient should henceforth be careful when climbing, since the biomechanical model showed that the remaining flexor digitorum profundus tendon was overused.We present two recent cases of spontaneous rupture of both index finger extensor digitorum communis and extensor indices proprius tendons caused by a dorsal carpus osteophyte. Both patients had a history of scaphoid fracture non-union with evolution to scaphoid non-union advanced collapse (SNAC) of the wrist. These two cases were treated surgically with a 3-corner arthrodesis, and an interposition of a fragment of one of both ruptured tendons together with a tendon transfer of a supernumerary extensor digitorum communis of the third finger. The interposed tendon fragment was sutured with a Pulvertaft weave proximally and end-to-end distally. The supernumerary tendon was added as reinforcement to this construction. At 6-month and 14-month follow-up, the patients had a slight decrease in range of motion and functionality without hindering the activities of daily living and a great improvement in strength. Isolated extension of the index finger was possible minimum 6 months postoperatively. Spontaneous tendon ruptures of the finger extensors are not common but were described earlier in literature. Recent literature described that underlying cause of a spontaneous tendon rupture should always be corrected in order to prevent or at least delay future ruptures. To our knowledge, this is a rare type of complication and this kind of treatment has never been reported in literature.This study investigated the advanced treatment of secondary effluent organic matters (EfOM) from an industrial park wastewater treatment plant (IPWTP) by Fenton oxidation process and its combination with biological aerated filter (BAF). The constituents of EfOM were characterized by using fluorescence excitation-emission matrix, and the results showed that the major components included aromatic proteins, soluble microbial products, humic and fulvic acid-like substances, and compounds associated with fluorescent region of Ex 250-300 nm/Em 600-700 nm. The EfOM was strongly resistant to biodegradation (biochemical oxygen demand (BOD5)chemical oxygen demand (COD) ratio at 0.11), resulting in less than 15% dissolved organic carbon (DOC) removal efficiency by the BAF reactor. The advanced treatment of EfOM by Fenton oxidation process led to maximum ~50% mineralization efficiency of EfOM under the optimal conditions of 2.0 mM FeII, 10 mM H2O2, pH 3.0 and 3.0 h of the reaction time. Particularly, Fenton oxidation treatment effectively improved the biodegradability of EfOM in the IPWTP secondary effluents, e.
