연구실 소개
조민철 교수의 연구실은 주로 비만, 당뇨, 신장질환 등 대사질환과 관련된 분자 기전을 규명하고, 이를 바탕으로 새로운 치료 타겟을 도출하는 데 초점을 맞추고 있습니다. 특히 레스베라트롤과 비타민 D의 대사적 영향을 중심으로 신진대사 및 요로기능 장애에 미치는 영향을 실험적으로 분석하고 있으며, 신경조절 및 근육 기능 조절 메커니즘을 이해하는 데에도 기여하고 있습니다. 최근에는 호르몬 및 영양소의 역할을 통해 만성질환의 예방 및 관리 전략을 모색하고 있습니다.

15As deep neural networks get more complex and input datasets get larger, it can take days or even weeks to train a deep neural network to the desired accuracy. Therefore, enabling distributed deep learning at a massive scale is critical since it offers the potential to reduce the training time from weeks to hours. In this article, we present BlueConnect, an efficient communication library for distributed deep learning that is highly optimized for popular GPU-based platforms. BlueConnect decompose
Abstract Ozone consumption by water can be characterized by the instantaneous ozone demand (IOD) and a pseudo first order decay constant. Utilizing the flow injection analytical system for measuring IOD, the instantaneous ozone demand characteristics of two river waters (Korea) were investigated, utilizing a •OH probe compound and •OH scavenger, and were compared with those of two commercial humic acids (the Suwannee River humic acid and Aldrich humic acid). The major findings were as follows; (
Generally, improvement of micturition symptoms, QoL and PVR in patients with DU appears to be maintained up to 5 years after PV or HoLEP. Deterioration of voiding symptoms and urinary flow rate at long-term follow-up visits after PV or HoLEP was more pronounced in patients with LUTS/BPH with DU than in those without DU. Patients with BPH with DU may benefit from more complete removal of prostatic adenoma by HoLEP and greater baseline bladder contractility in terms of micturition symptoms and QoL
Improvements in LUTS, Qmax, and BVE can maintain up to 3 years after HPS or HoLEP for LUTS/BPH, irrespective of the presence or absence of preoperative DU. Although HoLEP may provide more durable improvement of VS in men with DU than HPS, there seems to be no difference in improvement of QOL or Qmax or BVE between HPS and HoLEP.
The LIM kinases (LIMK1 and LIMK2), known as downstream effectors, and the Rho-associated protein kinase (ROCK), a regulator of actin dynamics, have effects on a diverse set of cellular functions. The LIM kinases are involved in the function of the male urogenital system by smooth muscle contraction via phosphorylation of cofilin and subsequent actin cytoskeleton reorganization. Although LIMK1 and LIMK2 share sequence similarities as serine protein kinases, different tissue distribution patterns
Vitamin D deficiency in men with LUTS may play a role in aggravated overactive bladder (OAB) symptoms, especially in winter. Increasing vitamin D level in patients with vitamin D deficiency appears to alleviate OAB symptoms.
Our serial followup data suggest that storage symptom improvement was maintained throughout the long-term postoperative period for prostate photoselective laser vaporization with a 120 W high performance system and holmium laser enucleation without any difference between the 2 surgeries. Also, more severe storage symptoms at baseline and a more severe BOOI predicted improved storage symptoms in the long term after each surgery.
Erectile dysfunction (ED) is a common disorder that can jeopardize quality of life and the partnership of patients and their sexual partners. The advent of oral phosphodiesterase type 5 inhibitors (PDE5Is) has revolutionized a treatment for ED, and they are recognized as the first-line therapy for ED, regardless of its etiology. Mirodenafil, a second-generation PDE5I, has biochemical profiles such as high affinity for PDE5 and high selectivity for PDE5 over other PDE isoforms, compared to other
We evaluated whether chronic administration of LIMK2-inhibitors could improve erectile function by alleviating CVOD through suppressing cavernosal fibrosis in a rat model of cavernosal nerve crush-injury (CNCI). Forty-two 12-week-old rats were equally categorized into the three groups: sham-surgery (S), CNCI (I), and CNCI treated with LIMK2-inhibitors (L). The L-group was treated with daily intraperitoneal injection of LIMK2-inhibitors (10.0 mg/kg) for 30-days after surgery. Erectile function wa
This study aimed to determine serial changes in self-assessed goal achievement (SAGA) and treatment satisfaction after HoLEP, to identify correlations between the two, and to compare them with results assessed by traditional outcome measures. For a total of 170 patients, outcomes were evaluated serially at postoperative 1-, 3-, 6-, and 12-months using IPSS, OABSS, SAGA questionnaires and uroflowmetry. The SAGA questionnaire consisted of five questions including one open-ended question (self-asse
Our data indicate that chronic inhibition of JNK and LIMK2 can restore cavernous-veno-occlusive-function by suppressing cavernous-apoptosis and cavernous-fibrosis, comparable to the results by PDE5-inhibitors. Chronic inhibition of JNK and LIMK2 might be a potential mechanism-specific targeted therapy for cavernous-veno-occlusive-dysfunction induced by cavernous nerve-injury.
Our data indicate that LMR can play an independent predictive role in the detection of CSPCs at initial 12-core-TRUS-Bx compared with ELR. The predictive role of the LMR appears to be significant for men with larger prostate volume rather than those with smaller prostate volume.
