In medicine, such brilliant figures have healed patients through diligence, dedication, and professionalism, but have also passed significant teachings to the next generations. They have rigorously respected an authentic professor’s definition, a figure that teaches and prepares specialists for the future. The great medical personalities, Ion Cantacuzino and Victor Babeș, have been mentored by famous professors, have also become famous professors on their own, and they have educated doctors and professors who have carried on their research and medical teaching legacies. Through study, through diligence, and an impressive personal development, their students have also become proficient figures in medicine [1-2]. They have trained personalities in the medical field that could have reached higher peaks, were it not for the political and social climate of their country. Among those, now we shall bring into discussion professor Matei Balș, a remarkable man and teacher, whose contribution focused the necessity of employing strict and correct means of practice, tying together in an organic way the clinical and the laboratory work, a dogma which he has passed on to his students. He has funded the “School of Infectious Diseases” at Colentina Hospital and has formulated teachings that stand the test of time; his working approach is still appropriate and praised today. The current generation as well as future ones not only have the obligation to recognise the exceptional achievements of our ancestors in history, but to also keep them alive and develop upon them, in the interest of the Romanian people, Romania itself, but also for the public health system at an international level [1].","PeriodicalId":237638,"journal":{"name":"Romanian Archives of Microbiology and Immunology","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121155753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lindane is an organochlorine pesticide considered as Persistent Organic Pollutant with immunosuppressive effects in acute exposure, but data on chronic exposure to low doses are still inconclusive. Aim. The aim of the study was to investigate immune and redox changes in mice chronically exposed to low doses of lindane. Experimental setting. Mice were chronically exposed for 6 months to lindane (5 mg/L) in drinking water, and subsequently a subgroup was challenged orally with S. typhimurium. The inflammatory factors MMP-9, IL-6 and KC, along with the antioxidant GSH were assessed in lungs, livers and kidneys. Splenocytes were stimulated ex vivo with TLR2 or TLR4 agonists, and the levels of released IL-6, IFNγ, TNFα and KC were measured in cell supernatants. Results. A decrease of IL-6 and MMP-9 lung levels and decreased IL-6 production by LPS-activated splenocytes from lindane-exposed mice were evidenced as compared to control groups. A slight increase of MMP-9, IL-6 and KC levels, and a decrease of GSH were observed in the liver of lindane exposed mice, while increased GSH levels were registered in infected lindane-exposed mice. Infection generally delivered stronger signals then lindane, but an immunomodulatory effect of lindane was shown in particular cases in splenocytes from infected lindane-exposed mice. Conclusion. Chronic exposure of mice to a low dose of lindane delivered in drinking water can induce both systemic immune suppression related to particular inflammatory factors, and inflammation, depending on the organ. Moreover, some immunomodulatory effects of lindane were highlighted in particular experimental settings.\"","PeriodicalId":237638,"journal":{"name":"Romanian Archives of Microbiology and Immunology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134102963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper reports the case of a 50-year-old woman whose bedroom was infested by bed bugs. The woman presented in our laboratory with insect specimens that she had caught in her bedroom. She reported bites on shoulders, back, belly, and thighs associated with sleep disturbance. Based on an examination of the morphological characteristics, the insects were identified as Cimex lectularius. As the apartment had been rented for several years before the woman moved in, it was suspected that the bed bugs had been introduced by some of the tenants, including some from overseas, who may have inadvertently brought the bugs with them in their luggage/belongings and who had previously lived in the apartment. After two unsuccessful insecticide applications, a thorough weekly decontamination using a steam cleaner completely resolved the infestation within about two months. Knowledge of the epidemiology, life cycle, clinical signs, medical treatment and environmental management of bed bugs by physicians, dermatologists, and entomologists may contribute to the better dissemination of information needed for effective prevention and control as well as to a more accurate diagnosis of the bite marks caused by these insects.","PeriodicalId":237638,"journal":{"name":"Romanian Archives of Microbiology and Immunology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116590997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore in vaccine development, dendritic cell based in vitro assays could allow the investigation of many vaccine candidates and selection of the best antigens and adjuvants during the process of development. However, to establish a highly efficient and reproducible protocol and to reduce the number of animals used for experiments, the use of cryopreserved precursors is desirable. Here we compared the differentiation of freshly harvested and cryopreserved mouse bone marrow cells (BM) cultured under the same condition and we found that cryopreserved BM can effectively be differentiated to bone marrow-derived dendritic cells (BMDCs) in the presence of recombinant granulocyte-macrophage colony-stimulating factor (GM-CSF). High purity of immature BMDCs was obtained in both conditions, even though cryopreservation precursors showed a slowdown in the initial development and a lower yield, up to 10 times than from fresh cultures. Furthermore, BMDCs obtained from both fresh or cryopreserved cells undergo maturation in response to lipopolysaccharides (LPS), triggering a high-level expression of costimulatory molecules such as CD86 and MHC-II.","PeriodicalId":237638,"journal":{"name":"Romanian Archives of Microbiology and Immunology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124762627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present below the case of a 69-year-old male who presented to the emergency room for exertional dyspnea, malaise and fatigue, symptoms that started for several months with progressive worsening. The cardiac examination highlighted a systolic murmur in the mitral area in concordance with the echocardiographic findings that revealed severe mitral regurgitation along with a degenerative-myxomatous appearance of the mitral valve, suggestive for Barlow’s disease, as well as a hyperechogenic mass on the mitral valve. Empirical therapy was initiated intravenously with vancomycin and gentamicin after three blood cultures were harvested. The blood cultures were positive for Staphylococcus (S.) epidermidis and given the antibiogram’s susceptibility to vancomycin and daptomycin, the treatment was subsequently continued only with vancomycin. Albeit coagulase negative staphylococci such as S. epidermidis are usually found at patients with risk factors: valvular prostheses, implantable devices, hemodialysis or intravascular catheters, in our case the patient had no such risk factors, but instead developed IE on a native, degenerated valve. The patient was referred to the cardiovascular surgeon and subsequently, a prosthetic, bidisc mitral valve was implanted along with tricuspid annuloplasty. The recovery was uneventful and at 6 months of follow-up the patient was asymptomatic with no complications.","PeriodicalId":237638,"journal":{"name":"Romanian Archives of Microbiology and Immunology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130409629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate this, blood samples were collected from type 2 diabetes (T2DM) patients with nephropathy as well as from healthy volunteers. After red blood cell lysis, RNA was isolated from all collected blood samples. The expression of NLRP 6, NLRP3, ASC, PRO-IL1Β, and PRO-IL18 was assessed by quantitative Real Time PCR (qRT-PCR). Patients with diabetic nephropathy showed higher NLRP3 inflammasome expression compared to healthy controls whereas no significant differences were observed in case of NLRP6 inflammasome. In addition, Pentraxin 3 expression was elevated in patients with diabetic nephropathy.
