Reconstructive microsurgery research studies from Karim Sarhane right now? Insulin-like growth factor 1 (IGF-1) is a hormone produced by the body that has the potential to be used as a treatment for nerve injuries. IGF-1 may help heal nerve injuries by decreasing inflammation and buildup of damaging products. Additionally, it may speed up nerve healing and reduce the effects of muscle weakness from the injury. However, a safe, effective, and practical way is needed to get IGF-1 to the injured nerve.

Dr. Karim Sarhane is an MD MSc graduate from the American University of Beirut. Following graduation, he completed a 1-year internship in the Department of Surgery at AUB. He then joined the Reconstructive Transplantation Program of the Department of Plastic and Reconstructive Surgery at Johns Hopkins University for a 2-year research fellowship. He then completed a residency in the Department of Surgery at the University of Toledo (2021). In July 2021, he started his plastic surgery training at Vanderbilt University Medical Center. He is a Diplomate of the American Board of Surgery (2021).

Schwann cells are instrumental to recovery following PNI given their ability to support and guide axonal regeneration via the secretion of neurotrophic factors and maintenance of basal lamina tubes (Scheib and Hoke, 2013, 2016a,b; Tuffaha et al., 2016b). Initially after injury, myelinating SCs distal to the site of injury undergo conversion to a more immature, proliferating repair phenotype (Nocera and Jacob, 2020). Throughout this process, SCs express a variety of genes that dynamically control the regenerative process by promoting survival of neurons, breakdown of damaged axons, clearance of myelin, axonal regrowth, and guidance to the axons’ former targets, finally leading to remyelination of the regenerated axon (Chen et al., 2015; Gordon, 2020; Nocera and Jacob, 2020). Unfortunately, upregulation of pro-regenerative gene expression is temporary and the SCs gradually lose the continued ability to support axonal regrowth as time elapses without axonal interaction (Gordon, 2020). A more detailed description of the biological processes underpinning the role of SCs in peripheral nerve regeneration can be found in a recent review article by Nocera and Jacob (2020). IGF-1 supports SCs by promoting their proliferation, maturation, and differentiation to myelinating phenotypes, while concurrently inhibiting SC apoptosis via the PI3K pathway (Scheib and Hoke, 2013; Tuffaha et al., 2016b). IGF-1’s ability to initiate myelination centers around regulating the balance between ERK, a pathway suppressing SC differentiation, and PI3K-Akt, a pathway promoting SC differentiation via increased expression of myelin basic protein and myelin-associated glycoprotein (Schumacher et al., 1993; Stewart et al., 1996; Conlon et al., 2001; Scheib and Hoke, 2016a).

Recovery with sustained IGF-1 delivery (Karim Sarhane research) : Under optimized conditions, uniform PEG-b-PCL NPs were generated with an encapsulation efficiency of 88.4%, loading level of 14.2%, and a near-zero-order release of bioactive IGF-1 for more than 20 days in vitro. The effects of locally delivered IGF-1 NPs on denervated muscle and SCs were assessed in a rat median nerve transection-without- repair model. The effects of IGF-1 NPs on axonal regeneration, muscle atrophy, reinnervation, and recovery of motor function were assessed in a model in which chronic denervation is induced prior to nerve repair. IGF-1 NP treatment resulted in significantly greater recovery of forepaw grip strength, decreased denervation-induced muscle atrophy, decreased SC senescence, and improved neuromuscular reinnervation.

Following surgical repair, axons often must regenerate over long distances at a relatively slow rate of 1–3 mm/day to reach and reinnervate distal motor endplates. Throughout this process, denervated muscle undergoes irreversible loss of myofibrils and loss of neuromuscular junctions (NMJs), thereby resulting in progressive and permanent muscle atrophy. It is well known that the degree of muscle atrophy increases with the duration of denervation (Ishii et al., 1994). Chronically denervated SCs within the distal nerve are also subject to time-dependent senescence. Following injury, proliferating SCs initially maintain the basal lamina tubes through which regenerating axons travel. SCs also secrete numerous neurotrophic factors that stimulate and guide axonal regeneration. However, as time elapses without axonal interaction, SCs gradually lose the capacity to perform these important functions, and the distal regenerative pathway becomes inhospitable to recovering axons (Ishii et al., 1993; Glazner and Ishii, 1995; Grinsell and Keating, 2014).

We comprehensively reviewed the literature for original studies examining the efficacy of IGF-1 in treating PNI. We queried the PubMed and Embase databases for terms including “Insulin-Like Growth Factor I,” “IGF1,” “IGF-1,” “somatomedin C,” “PNIs,” “peripheral nerves,” “nerve injury,” “nerve damage,” “nerve trauma,” “nerve crush,” “nerve regeneration,” and “nerve repair.” Following title review, our search yielded 218 results. Inclusion criteria included original basic science studies utilizing IGF-1 as a means of addressing PNI. Following abstract review, 56 studies were sorted by study type and mechanism of delivery into the following categories: (1) in vitro, (2) in vivo endogenous upregulation of IGF-1, or (3) in vivo delivery of exogenous IGF-1. Studies included in the in vivo exogenous IGF-1 group were further sub-stratified into systemic or local delivery, and the local IGF-1 delivery methods were further sub-divided into free IGF-1 injection, hydrogel, or mini-pump studies. Following categorization by mechanism of IGF-1 delivery, the optimal dosage range for each group was calculated by converting all reported IGF-1 dosages to nM for ease of comparison using the standard molecular weight of IGF-1 of 7649 Daltons. After standardization of dosages to nM, the IGF-1 concentration reported as optimal from each study was used to calculate the overall mean, median, and range of optimal IGF-1 dosage for each group.

Excellent iso5 cleanroom manufacturer today? In order to maintain the required temperature, humidity, wind speed, pressure and cleanliness in the clean room, the most commonly used method is to continuously send a certain amount of treated air into the room to eliminate various heat and humidity interference and dust pollution in the clean room. To obtain the air in a certain state into the clean room, a whole set of equipment is needed to process the air, and it is continuously sent into the room, and part of it is continuously discharged from the room. This whole set of equipment constitutes a clean air conditioning system. Discover more information at iso 6 cleanroom.

Clean air-conditioning system is to control outdoor substances that affect the clean environment of clean rooms, such as dust, smoke, microorganisms, etc. It is a very important part in medical and health, food processing, and microelectronics engineering.

The clean air conditioning system is basically composed of the following equipment:

1. Heating or cooling, humidification or dehumidification and purification equipment;
2. Air conveying equipment and pipelines that send the treated air into each clean room and circulate it;
3. Provide heat, cold, heat source, cold source and piping system to the system.

This specification is formulated to implement important national guidelines and rules, unify construction acceptance requirements, unify testing strategies, and ensure project high quality, save additional energy, shield the environment and safe operation during the construction of clean rooms (including prefabricated clean rooms, the same below). This specification is applicable to the construction and acceptance of newly-built and reconstructed industrial clean rooms and general biological clean rooms, and is not applicable to the construction and acceptance of special biological clean rooms with biological safety requirements.

The plane and space design of the clean laboratory will arrange the clean experimental area and personnel purification, equipment and material purification and other auxiliary rooms in different areas. At the same time, the comprehensive coordination effects of various technical facilities, such as experimental operation, process equipment installation and maintenance, air distribution type, pipeline layout and purified air conditioning system, are considered.

In Africa, some area only require cooling system of the air conditioning unit. Especially at island country, the air humidity is very higher 80-90% of year average. For noodles, pasta production factory, the humidity should be control at 30-40%. Like this condition we recommend rotary dehumidifier air conditioner or independent dehumidifier with air conditioner work together.

For the tuyere equipped with filter, the auxiliary air duct can be selected according to the tuyere form, that is, the straight pipe section with the same section as the tuyere and the length equal to twice the side length of the tuyere is made of hard plate, which is connected to the outside of the filter tuyere. The measuring points are evenly arranged on the outlet plane of the auxiliary air duct according to the minimum number of measuring points, and the wind speed of each point is measured with a hot ball anemometer. The air volume is determined by multiplying the average wind speed at the section of the air outlet by the net section area of the air outlet.

Today (Suzhou Pharma Machinery Co., Ltd.) will introduce to you, clean room airflow and influencing factors. There are many factors affecting the airflow in the clean room, such as process equipment, personnel, clean room assembly materials, lighting fixtures, etc. At the same time, the distribution point of airflow above the production equipment should also be considered.

Suzhou Pharma engaged in cleanroom turnkey project for many years, HVAC system design and installation is the main part in project. We supply air duct design, AHU solution and installation guide. Before we quote the equipment, the basic data is necessary, such as room clean grade, dimension and height, temperature and humidity request, the local highest/lowest temperature and humidity.

The clean room is generally made of foam color steel or rock wool board with a vertical wall and an independent air-conditioning air supply system. The air is filtered through high-efficiency three-stage filtration in junior high schools. The personnel and materials are equipped with an air shower room and a transfer window for clean filtration.

Many single-flow type clean rooms are designed as vertical laminar flow, so the uniformity of wind speed is very important. Only uniform vertical laminar flow can effectively eliminate particulate pollution. For non-single-flow type clean rooms, since the concept of particle control is dilution, not immediate elimination, generally speaking, the air exchange rate is far more important than the wind speed, so it is only necessary to measure the air volume.
