COVID GEAS: COVID-19 National Survey in Patients With Systemic Autoimmune Diseases. Front Med (Lausanne) 2022; 8:808608. [PMID: 35155485 PMCID: PMC8828974 DOI: 10.3389/fmed.2021.808608] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 12/07/2021] [Indexed: 01/08/2023] Open
Abstract
Objectives COVID-19 outcomes in population with systemic autoimmune diseases (SAD) remain poorly understood. The aim was to examine demographic and clinical factors associated with COVID-19 infection in people with rheumatic disease. Methods Two phases cross-sectional survey of individuals with rheumatic disease in April 2020 and October 2020. COVID infection, severity of disease, age, sex, smoking status, underlying rheumatic disease diagnosis, comorbidities and rheumatic disease medications taken immediately prior to infection were analyzed. Results A total of 1,529 individuals with autoimmunity disease diagnosis were included. Out of 50 positive patients, 21 required telephone medical assistance, 16 received assessment by primary care physician, 9 were evaluated in Emergency Department and 4 patient required hospitalization. Multivariate analysis was performed without obtaining differences in any of the systemic autoimmune diseases. Regarding the treatments, significant differences were found (p 0.011) in the treatment with anti-TNF-alpha agents with OR 3.422 (1.322–8.858) and a trend to significance (p 0.094) was observed in patients receiving mycophenolate treatment [OR 2.016 (0.996–4-081)]. Conclusions Anti-TNF-alpha treatment was associated with more than 3-fold risk of suffering from SARS-CoV-2 infection, although in all cases infection was mild. Cumulative incidence in patients with SAD was up to 5 times higher than general population but with great differences between autoimmune diseases.

Abstract
Aportamos citas de cinco plantas alóctonas nuevas para Europa —Commelina erecta, Cylindropuntia fulgida, Dasylirion serratifolium, xGraptosedum y Senecio crassissimus—, dos nuevas para la península ibérica —Lobelia laxiflora subsp. angustifolia y Pennisetum flaccidum— y cuatro nuevas para Cataluña —Dimorphotheca fruticosa, xGasteraloe beguinii, Opuntia elatior y Tradescantia sillamontana—. También presentamos nuevos datos sobre diez plantas poco citadas en Cataluña. En las últimas décadas el cultivo de plantas ornamentales constituye la principal causa de introducción de especies alóctonas a escala mundial, algunas de las cuales son potencialmente invasoras. La mayoría de las plantas que constan en este trabajo son escapadas de cultivos o provienen de vertidos de restos de jardinería. Algunas especies se encuentran localmente naturalizadas y en algún caso podrían presentar un comportamiento invasor.

Abstract
Las guerras y las actividades militares en general tienen un gran impacto en los humanos y en la biodiversidad, que se resume aquí brevemente. Algunos efectos adversos, aunque no éticamente aceptables en principio, producen sin embargo algunas oportunidades que, en última instancia, dieron lugar a acciones beneficiosas para la conservación de las plantas. Una breve revisión de diferentes casos de estudio alrededor del mundo y en diferentes períodos históricos muestran cómo las zonas y actividades militares pueden actuar de reservas naturales si se toman las decisiones administrativas apropiadas (con base científica) en un marco más amplio de conservación coordinada con otras áreas de la intervención humana en la biosfera.

Abstract
The aim of this study was to describe the clinical characteristics of ANCA-associated vasculitides (AAV) at presentation, in a wide cohort of Spanish patients, and to analyze the impact of the vasculitis type, ANCA specificity, prognostic factors, and treatments administered at diagnosis, in the outcome.A total of 450 patients diagnosed between January 1990 and January 2014 in 20 Hospitals from Spain were included. Altogether, 40.9% had granulomatosis with polyangiitis (GPA), 37.1% microscopic polyangiitis (MPA), and 22% eosinophilic granulomatosis with polyangiitis (EGPA). The mean age at diagnosis was 55.6 ± 17.3 years, patients with MPA being significantly older (P < 0.001). Fever, arthralgia, weight loss, respiratory, and ear-nose-throat (ENT) symptoms, were the most common at disease onset. ANCAs tested positive in 86.4% of cases: 36.2% C-ANCA-PR3 and 50.2% P-ANCA-MPO. P-ANCA-MPO was significantly associated with an increased risk for renal disease (OR 2.6, P < 0.001) and alveolar hemorrhage (OR 2, P = 0.010), while C-ANCA-PR3 was significantly associated with an increased risk for ENT (OR 3.4, P < 0.001) and ocular involvement (OR 2.3, P = 0.002). All patients received corticosteroids (CS) and 74.9% cyclophosphamide (CYC). The median follow-up was 82 months (IQR 100.4). Over this period 39.9% of patients suffered bacterial infections and 14.6% opportunistic infections, both being most prevalent in patients with high-cumulated doses of CYC and CS (P < 0.001). Relapses were recorded in 36.4% of cases with a mean rate of 2.5 ± 2.3, and were more frequent in patients with C-ANCA-PR3 (P = 0.012). The initial disease severity was significantly associated with mortality but not with the occurrence of relapses. One hundred twenty-nine (28.7%) patients (74 MPA, 41 GPA, 14 EGPA) died. The mean survival was 58 months (IQR 105) and was significantly lower for patients with MPA (P < 0.001). Factors independently related to death were renal involvement (P = 0.010), cardiac failure (P = 0.029) and age over 65 years old (P < 0.001) at disease onset, and bacterial infections (P < 0.001). An improved outcome with significant decrease in mortality and treatment-related morbidity was observed in patients diagnosed after 2000, and was related to the implementation of less toxic regimens adapted to the disease activity and stage, and a drastic reduction in the cumulated CYC and CS dose.

Abstract
Helichrysum italicum es una especie con una amplia distribución en la cuenca Mediterránea, la cual ha recibido tratamientos taxonómicos controvertidos a nivel infraespecifico debido a su variabilidad morfológica. En este trabajo realizamos un detallado análisis multivariante de los caracteres morfológicos sobre la base de un muestreo exhaustivo de H. italicum. Integrando datos moleculares y corológicos previamente publicados con los datos morfológicos obtenidos, se presenta una revisión del tratamiento taxonómico para todo el complejo H. italicum. Por un lado, los resultados obtenidos sugieren que las poblaciones de H. italicum subsp. microphyllum localizadas en la montaña de Mallorca deben ser consideradas como una especie independiente, descrita aquí como Helichrysum massanellanum. Por otro lado, las subespecies de H. italicum son recircunscritas. Se propone una nueva combinación, H. italicum subsp. tyrrhenicum, un taxón que comprende poblaciones de Córcega, Cerdeña, la costa de Mallorca y el islote de Dragonera, mientras que la subsp. microphyllum queda restringida a la isla de Creta. Con estas modificaciones sustanciales, se presenta un tratamiento taxonómico completo y nuevo para este grupo, incluyendo una clave de identificación, sinónimos, descripciones morfológicas, áreas de distribución y caracterización del hábitat.

Abstract
OBJECTIVES The current knowledge of the influence of systemic sclerosis (SSc) risk loci in the clinical sub-phenotypes is still limited. The main limitation lies in the low frequency of some sub-phenotypes which could be solved by replication studies in independent cohorts and meta-analysis between studies. In this regard, CCR6 gene variants have been recently associated with anti-topoisomerase I positive (ATA+) production in SSc patients in a candidate gene study. This gene has been proposed to have a critical role in IL-17-driven autoimmunity in human diseases. METHODS In order to confirm the association between CCR6 and ATA+ SSc patients, we performed an independent replication study in populations of European ancestry. We studied two CCR6 genetic variants (rs968334 and rs3093024) in a total of 901 ATA+ SSc cases, 3,258 ATA- SSc cases and 7,865 healthy controls and compared allelic frequencies for those SNPs in ATA+ SSc with healthy controls and also with ATA- SSc patients. RESULTS The comparison performed between ATA+ SSc patients and healthy controls showed significant association with SNP rs968334 (p=4.88x10(-2), OR=1.11). When we compared ATA+ SSc cases with ATA- SSc, both SNPs, rs3093024 and rs968334, showed significant associations (p=2.89x10(-2), OR=1.13; p=1.69x10(-2), OR=1.15). Finally, in order to increase even more sample size and statistical power, we meta-analysed our study with the previous reported and found a significant association between SNP rs3093024 and ATA+ SSc patients (p=1.00x10(-4), OR=1.16) comparing with healthy controls. CONCLUSIONS Our work confirms the association of CCR6 gene and ATA+ SSc patients.

Abstract
Peak age at onset of systemic sclerosis (SSc) is between 20 and 50 years, although SSc is also described in both young and elderly patients. We conducted the present study to determine if age at disease onset modulates the clinical characteristics and outcome of SSc patients. The Spanish Scleroderma Study Group recruited 1037 patients with a mean follow-up of 5.2 ± 6.8 years. Based on the mean ± 1 standard deviation (SD) of age at disease onset (45 ± 15 yr) of the whole series, patients were classified into 3 groups: age ≤ 30 years (early onset), age between 31 and 59 years (standard onset), and age ≥ 60 years (late onset). We compared initial and cumulative manifestations, immunologic features, and death rates. The early-onset group included 195 patients; standard-onset group, 651; and late-onset, 191 patients. The early-onset group had a higher prevalence of esophageal involvement (72% in early-onset compared with 67% in standard-onset and 56% in late-onset; p = 0.004), and myositis (11%, 7.2%, and 2.9%, respectively; p = 0.009), but a lower prevalence of centromere antibodies (33%, 46%, and 47%, respectively; p = 0.007). In contrast, late-onset SSc was characterized by a lower prevalence of digital ulcers (54%, 41%, and 34%, respectively; p < 0.001) but higher rates of heart conduction system abnormalities (9%, 13%, and 21%, respectively; p = 0.004). Pulmonary hypertension was found in 25% of elderly patients and in 12% of the youngest patients (p = 0.010). After correction for the population effects of age and sex, standardized mortality ratio was shown to be higher in younger patients. The results of the present study confirm that age at disease onset is associated with differences in clinical presentation and outcome in SSc patients.

Abstract
Nutrition is the basis of human physiological processes. Inadequate nutrition can lead to dysfunction in the metabolic chain links. One of the most important micronutrients is zinc, as evidenced by its wide range of carriers in the body. Zinc intake has a large margin in the current world population, may be 7 mg/d in the UK, reaching 15 mg/d in the U.S., although of course, the RDA's are set according to age, sex , physiological status (pregnancy, lactation, etc..), or disease. It is known that zinc is essential for the structure and function as well as DNA and enzymes, coenzymes, hormones and so on. Life is short, zinc, since the most rapidly absorbed and is transferred to tanks where it is stored, so the amount available zinc in the blood cannot be the amount "real". In this work we have done a mini-review of the passage of zinc by the body trying since their intake to their tour of the blood in both healthy and sick people.

Abstract
Introduction The purpose of this observational study was to analyze the rates, characteristics and associated risk factors of severe infections in patients with systemic autoimmune diseases (SAD) who were treated off-label with biological agents in daily practice. Methods The BIOGEAS registry is an ongoing Spanish prospective cohort study investigating the long-term safety and efficacy of the off-label use of biological agents in adult patients with severe, refractory SAD. Severe infections were defined according to previous studies as those that required intravenous treatment or that led to hospitalization or death. Patients contributed person-years of follow-up for the period in which they were treated with biological agents. Results A total of 344 patients with SAD treated with biological agents off-label were included in the Registry until July 2010. The first biological therapies included rituximab in 264 (77%) patients, infliximab in 37 (11%), etanercept in 21 (6%), adalimumab in 19 (5%), and 'other' agents in 3 (1%). Forty-five severe infections occurred in 37 patients after a mean follow-up of 26.76 months. These infections resulted in four deaths. The crude rate of severe infections was 90.9 events/1000 person-years (112.5 for rituximab, 76.9 for infliximab, 66.9 for adalimumab and 30.5 for etanercept respectively). In patients treated with more than two courses of rituximab, the crude rate of severe infection was 226.4 events/1000 person-years. A pathogen was identified in 24 (53%) severe infections. The most common sites of severe infection were the lower respiratory tract (39%), bacteremia/sepsis (20%) and the urinary tract (16%). There were no significant differences relating to gender, SAD, agent, other previous therapies, number of previous immunosuppressive agents received or other therapies administered concomitantly. Cox regression analysis showed that age (P = 0.015) was independently associated with an increased risk of severe infection. Survival curves showed a lower survival rate in patients with severe infections (log-rank and Breslow tests < 0.001). Conclusions The rates of severe infections in SAD patients with severe, refractory disease treated depended on the biological agent used, with the highest rates being observed for rituximab and the lowest for etanercept. The rate of infection was especially high in patients receiving three or more courses of rituximab. In patients with severe infections, survival was significantly reduced. Older age was the only significant predictive factor of severe infection.

Abstract
Systemic venous pressure is elevated in right heart failure, and this elevation may be reflected in pulsatile venous flow when there is significant tricuspid regurgitation. The presence of this systolic reversed flow in the femoral and popliteal veins may result in major difficulties for diagnosis and treatment. We report the case of a patient with signs and symptoms of acute ischemia of the right lower limb with palpable pulse in the groin and popliteal fossa. Tricuspid regurgitation was suspected by clinical examination, and Doppler ultrasonographic examination of the extremity revealed pulsatile flow in the femoral and popliteal veins while the iliac arterial axis was occluded. A preoperative angiogram revealed an underlying iliac artery thrombosis, which was successfully treated.

Abstract
OBJECTIVE To evaluate compliance, side effects and the efficacy of a short course of chemoprophylaxis for tuberculosis with isoniazid plus rifampin during 3 months, compared with the classic course of isoniazid for 9 months. PATIENTS AND METHODS Prospective, comparative, randomized and open study of patients with the suitable criteria for chemoprophylaxis, in accordance with the guidelines of the Centers for Disease Control of 1990. Patients were divided into 2 groups: the group of isoniazid plus rifampin, received isoniazid (300 mg per day) plus rifampin (600 mg per day) for 3 months, and the group of isoniazid, that received isoniazid at a dose of 300 mg per day for 9 months. RESULTS 238 patients were included, of which 42 refused chemoprophylaxis. Of the remaining 196 patients, 98 were included in each group. Both groups were comparable at base level. The side effects, neither light nor severe showed significant differences. The appearance of adverse effects obliged the suspension of treatment in 7 patients in group isoniazid and of 9 patients in group isoniazid plus rifampin. Three patients in group isoniazid plus rifampin and 11 in group isoniazid stopped treatment (OR 4.14, 95% CI 1.02-19.45; p = 0.04). Efficacy was comparable in the two groups; only one case of tuberculosis was detected in a patient who gave up chemoprophylaxis at day 30. CONCLUSIONS Tolerance in group isoniazid plus rifampin compared with group I was similar. Compliance was better in the short-term group with a lower percentage of abandonment. On comparing, both groups have shown similar efficacy in preventing the appearance of tuberculosis.

Abstract
BACKGROUND The decrease in the time spent in hospital of patients who have undergone surgery lessens wound observation time, and thus could underestimate the true rates of surgical wound infection (SWI). The aim of this study was to assess the use of a programme to detect SWI, by carrying out a control 30 days after patients have been discharged from hospital. PATIENTS AND METHODS A study of a prospective cohort of 2,015 patients who were operated in 6 surgical services at a general hospital, was carried out to detect the incidence of SWI. The control at one month after discharge from hospital was done through a telephone survey using a specific questionnaire. RESULTS SWI incidence was observed in 134 patients (6.7%), 38% of which were detected on the month after discharge from hospital. In the postoperatory control the major SWI rates were detected in the clean procedures and in the clean-contaminated procedures with 46% and 37%, respectively. The telephone interview enabled contact with 72.3% of the patients intervened. CONCLUSIONS The post-discharge control of patients who have undergone surgery enabled the detection of more than a third of SWI cases. The telephone interview system has been effective in our study as a postdischarge method of the localization of patients.

Abstract
We report the case of a patient with Brucella melitensis osteomyelitis involving non-joint prosthetic implant of the femur. This is the first case published of osteomyelitis by Brucella sp. in a patient with prosthetic implant in bone and the second one with both intra- or extra-articular prosthetic bone implant. Brucella melitensis is a rare organism which causes osteomyelitis in patients with prosthetic hardware, and should be added to the list of suspected organisms responsible for this disease, especially in endemic areas of brucellosis.

Abstract
We conducted a prospective, noncomparative, multicenter study to assess the safety and efficacy of doxycycline and netilmicin in the treatment of human brucellosis. The study included 64 patients who had acute brucellosis without endocarditis or neurobrucellosis. The treatment schedule consisted of the administration of 100 mg of doxycycline (or 5 mg/[kg.d] if body weight < or = 40 kg) twice a day orally for 45 days, plus 300 mg of netilmicin (6 mg/[kg.d] if body weight < or = 50 kg) intramuscularly once daily for 7 days. Therapeutic failure was noted in 5 patients (7.7%; 95% confidence interval [CI], 2.5%-17.1%), of whom 2 had spondylitis, 1 had sacroiliitis, and 1 had a splenic abscess that required splenectomy. Relapse was noted in eight patients (12.5%; 95% CI, 5.6%-23.2%). When relapse was considered in combination with initial lack of efficacy, 13 patients (21.9%; 95% CI, 12.3%-33.9%) failed to respond to therapy. Fifteen patients (23%; 95% CI, 13.5%-35.2%) had adverse effects, and one patient (1.5%) had a treatment-limiting adverse effect. Combination therapy with netilmicin/doxycycline may be effective in treating acute brucellosis. However, prospective controlled trials must confirm these results.

Abstract
Brucellosis is a common zoonosis in many parts of the world; the best regimen for the treatment of brucellosis has not been clearly determined. We have carried out a multicenter, open, controlled trial in five general hospitals in Spain to compare the efficacy and safety of doxycycline and rifampin (DR) versus doxycycline and streptomycin (DS) for the treatment of human brucellosis. The study included 194 ambulatory or hospitalized patients with acute brucellosis, without endocarditis or neurobrucellosis. The diagnostic criterion was isolation of Brucella species from blood or other tissues (n = 120) or a standard tube agglutination titer of 1/160 or more for anti-Brucella antibodies with compatible clinical findings (n = 74). Patients were randomly assigned to receive either 100 mg of doxycycline twice daily plus rifampin, 900 mg/day, in a single morning dose for 45 days (DR group) or the same dose of doxycycline for 45 days plus streptomycin, 1 g/day, intramuscularly for 14 days (DS group). A lack of therapeutic efficacy developed in 8 of the 100 patients in the DR group (8%) and in 2 of the 94 patients in the DS group (2%)(P = 0.10). Relapses occurred in 16 of the 100 patients in the DR group (16%) but in only 5 of the 94 patients in the DS group (5.3%) (P = 0.02). When relapse was considered in combination with initial lack of efficacy, 26 patients in the DR group (24%) and 7 patients in the DS group (7.45%) failed to respond to therapy (P = 0.0016). In general, therapy was well tolerated and only four patients (4%) in the DR group and two (2%) in the DS group had episodes of adverse effects necessitating discontinuation of treatment (P> 0.2). We conclude that a doxycycline-and-rifampin regimen is less effective than the doxycycline-and-streptomycin regimen in patients with acute brucellosis.

Abstract
Absenteeism affects efficiency and costs of health care. Most of health workers are middle age women, whose climacteric symptoms may reduce their work capacity working at a public hospital in Santiago during 1992. Fifty-eight percent were postmenopausal and 34.8% of these were receiving hormone replacement therapy. Global absenteeism rate was 17.1 days/year. These figures were 14.8 days/year for premenopausal and 17.8 days/year for postmenopausal women (NS). Among the latter, those women receiving hormone replacement therapy had a significantly lower absenteeism rate (9.4 days/year compared to 20.4 days/year among those not receiving hormones). Osteoarticular diseases were responsible for 44.3% and psychiatric diseases for 18.1% of sick leaves. No differences in absenteeism were observed between different professional levels. We conclude that hormone replacement therapy is associated with a better working capacity in postmenopausal women.

Abstract
BACKGROUND The aim of this study was to determine whether a conclusion could be obtained through meta-analysis of the published trials on the relative efficacy of rifampicin and doxycycline versus streptomycin and doxycycline or another tetracycline (SD). METHODS The comparative and randomized trials identified by a search in the reference data base MEDLINE from 1967 to 1992 and through manual review of the articles cited in these studies or other reviews were included. The evaluation of quality was performed by a standardized scale. The differences in efficacy were expressed as odds ratio and the results were contrasted by the Mantel-Haenszel method. Heterogenicity was graphically analyzed by the Woolf method with an adjustment being made for small subgroups. The confidence intervals were calculated for each trial and for the combined data by the Cornfield method. RESULTS Six trials including 581 patients of whom 544 were considered evaluable were analyzed. In the RD treatment group 261 (242 valid) patients were included with 268 (253 valid) being included in the SD group. Five cases of initial therapeutic failure were observed in each group without significant differences. The secondary effects described were very variable. Nonetheless no secondary effects obliging discontinuation of treatment were presented in the RD group with only one in the SD group with no differences between the two groups. Recurrences were presented in 5% and 39% in the RD group and in 0 and 17% in the SD group. In total 37 (16%) in the former group and 13 (5%) in the latter group. The Mantel-Haenszel odds ratio with respect to recurrence was 3.81 (CI 95%, 1.82-8.17; p = 0.00009). The total number of cures was 196 (81%) in the RD group and 232 (92%) in the SD group (Mantel-Haenszel odds ratio 0.36; CI 95%, 1.19-0.64; p = 0.0004). The inclusion of the quality index of the trials did not modify the statistical significance achieved. CONCLUSIONS In human brucellosis the treatment of rifampicin and doxycycline presents a greater number of recurrence and lower number of cure than the classical treatment with streptomycin and tetracycline drugs.

Abstract
BACKGROUND The aim of this study was to determine the risk of active tuberculosis in intravenous drug addict (IVDA) patients seropositive and seronegative for the HIV. METHODS A retrospective study of a cohort of IVDA males in 2 drug addict detoxication communities was carried out. Patients with tuberculosis, under treatment or chemoprophylaxis for tuberculosis and those with a stay of less than 3 months were excluded. Patients included underwent a serologic study to detect antibodies versus HIV and a Mantoux test with 2 U. PPDRT23. Subjects who were HIV+ with a Mantoux test < 5 mm were given a delayed cutaneous sensitivity test with 7 antigens. The incidence index of tuberculosis was studied. Logistic regression analysis was performed to evaluate the relative risk of tuberculosis in HIV+ controlled by other variables (having been in prison, previous liver disease, country of origin, age, length of IVDA and length of follow up). RESULTS Of the 198 patients admitted 132 were included. Forty-seven were HIV+ and 85 HIV-. Fourteen of the former (30%) and 44 of the latter (51%) had a positive reaction to the Mantoux test (OR 0.4; confidence interval 95% 0.18-0.92; p < 0.05). Eight seropositive (17%) patients with a negative Mantoux test presented anergia to the delayed cutaneous sensitivity tests. After a mean follow up of 12.0 +/- 9.0 months, 4 patients out of the 47 HIV+ (8.5% or 6.93 cases/100 individuals/year; CI 95% 0.13-13.72) presented tuberculosis versus none of the 85 HIV- (p < 0.05) patients. Of the 4 patients diagnosed of tuberculosis, the initial reaction to the Mantoux test was negative in 2 (one pulmonary and the other milliar tuberculosis). Two of the 4 patients diagnosed of tuberculosis died. CONCLUSIONS The risk of active tuberculosis is specially high in HIV seropositive intravenous drug addicts. The response to the Mantoux test has little sensitivity for demonstration of tuberculous infection in HIV seropositive patients.

Abstract
Male and female winter-acclimatized carps were injected with insulin. This treatment resulted in a sharp decrease in the liver glycogen content. Although an increase in the ribosomal RNA level was also observed, a cell-free system obtained from the hormone-treated fish exhibited less amino acid incorporation activity as compared to the control fish. However, polysomes from insulin-treated fish exhibited a higher amino acid incorporating activity when a soluble fraction of untreated winter carps was used. Insulin induced a profound change in the cytoarchitecture of the winter carp hepatocyte. The cytoplasm and nuclei showed all the features of the summer carp liver cell. The nucleolar components were totally intermingled suggesting a high rate of gene expression as in the case of the summer-acclimatized fish.

Abstract
A cell-free system, active in protein synthesis, was constructed using ribosomes and supernatant factors isolated from the livers of winter-acclimatized carps. Upon seasonal adaptation, the hepatocytes of these fishes exhibited distinctive morphological features that were not sex dependent. The cytoarchitecture of the liver cell from summer carps is consistent with the cellular arrangements found when the rate of gene expression is high. During winter, several morphological features reveal that macromolecular synthetic activity may be clearly diminished.
