Abstract
INTRODUCTION Controversy exists in the literature about the best treatment for type III acromioclavicular dislocations. The aim of this study is to compare functional results between surgical and conservative treatment in type III acromioclavicular joint dislocations. MATERIAL AND METHOD We retrospectively evaluated the records of 30 patients from our area with acute type III acromioclavicular dislocations that were treated from January 1st, 2016 to December 31st, 2020. Fifteen patients were treated surgically and 15 conservatively. Follow-up mean time was 37.93 months in operative group and 35.73 months in non-operative group. Results obtained on the Constant score was the main variable analysed and results obtained on the Oxford score and the Visual Analogue Scale for pain were the secondary variables. Epidemiological variables were analysed, as well as range of mobility in injured shoulder and subjective and radiological variables (distance between the superior border of the acromion and the superior border of the clavicle's distal end and presence of osteoarthritis in the acromioclavicular joint). RESULTS Functional evaluation scores did not show differences between the two groups (Constant: operative 82/non-operative 86.38, p 0.412; Oxford: operative 42/non-operative 44.80, p 0.126) nor did Visual Analogue Scale (operative 1/non-operative 0.20, p 0.345). Subjective evaluation of the injured shoulder was excellent or good in 80% of the patients in both groups. Measurement of the distance between the superior border of the acromion and the superior border of the clavicle's distal end were significantly higher in non-operative group (operative 8.95/non-operative 14.21, p 0.008). CONCLUSIONS Although radiographic results were better in the surgical treatment group, functional evaluation scores did not show significant differences between the two groups. These results do not support the routine use of surgical treatment for grade III acromioclavicular dislocations.

Abstract
PURPOSE To examine the association of the single nucleotide polymorphism A1470T in the SLC16A1 gene with blood lactate accumulation during a graded exercise test and its associated metaboreflex. METHODS Forty-six Latin-American men (Age: 27 ± 6 years; Body fat: 17.5 ± 4.7%) performed a graded exercise test on a treadmill for the assessment of maximal oxygen uptake (VO2max), lactate threshold (LT), ventilatory threshold (VT) and the exercise intensity corresponding to maximal fat oxidation rate (FATmax), via capillary blood samples and indirect calorimetry. Genomic DNA was extracted from a peripheral blood sample. Genotyping assay was carried out by real-time polymerase chain reaction to identify the A1470T polymorphism (rs1049434). RESULTS Genotypes distribution were in Hardy-Weinberg equilibrium (X2 = 5.6, p > 0.05), observing allele frequencies of 0.47 and 0.53 for the A and T alleles, respectively. No difference in VO2max, body composition nor FATmax were observed across genotypes, whereas carriers of the TT genotype showed a higher LT (24.5 ± 2.2 vs. 15.6 ± 1.7 mL kg-1 min-1, p < 0.01) and VT in comparison to carriers of the AA + AT genotypes (32.5 ± 3.3 vs. 21.7 ± 1.5 mL kg-1 min-1, p < 0.01). Both, VO2max and the A1470T polymorphism were positively associated to the LT (R2 = 0.50, p < 0.01) and VT (R2 = 0.55, p < 0.01). Only VO2max was associated to FATmax (R2 = 0.39, p < 0.01). CONCLUSION Independently of cardiorespiratory fitness, the A1470T polymorphism is associated to blood lactate accumulation and its associated ventilatory response during submaximal intensity exercise. However, the A1470 polymorphism does not influence fat oxidation capacity during exercise in young men.

Abstract
Glucose and lipid metabolism regulation by the peroxisome proliferator-activated receptors (PPARs) has been extensively reported. However, the role of their polymorphisms remains unclear. OBJECTIVE To determine the relation between PPAR-γ2 rs1801282 (Pro12Ala) and PPAR-β/δ rs2016520 (+294T/C) polymorphisms and metabolic biomarkers in adults with type 2 diabetes (T2D). MATERIALS AND METHODS We included 314 patients with T2D. Information on anthropometric, fasting plasma glucose (FPG), HbA1c and lipid profile measurements was taken from clinical records. Genomic DNA was obtained from peripheral blood. End-point PCR was used for PPAR-γ2 rs1801282, while for PPAR-β/δ rs2016520 the PCR product was digested with Bsl-I enzyme. Data were compared with parametric or non-parametric tests. Multivariate models were used to adjust for covariates and interaction effects. RESULTS minor allele frequency was 12.42% for PPAR-γ2 rs1801282-G and 13.85% for PPAR-β/δ rs2016520-C. Both polymorphisms were related to waist circumference; they showed independent effects on HbA1c, while they interacted for FPG; carriers of both PPAR minor alleles had the highest values. Interactions between FPG and polymorphisms were identified in their relation to triglyceride level. CONCLUSIONS PPAR-γ2 rs1801282 and PPAR-β/δ rs2016520 polymorphisms are associated with anthropometric, glucose, and lipid metabolism biomarkers in T2D patients. Further research is required on the molecular mechanisms involved.

Abstract
Purpose: This work studies the interrelation of the first ventilatory threshold (VT1), the heart rate inflection point (HRIP), and the exercise intensity at which blood lactate started to accumulate (LIAB) or increased 1 mmol∙L-1 above baseline (LT+1.0); and examinee their association with the exercise intensity eliciting maximal fat oxidation (FATmax). Methods: Eighteen young men with obesity performed an incremental-load exercise test on a treadmill after overnight fasting. Gas exchange, heart rate, and blood lactate concentration were recorded. Linear regression analysis was used to determine the association among FATmax and AeT markers. A standard error of estimate (SEE) ≤9 beats∙min-1 and the concordance correlation coefficient (CCC) were used to examine the accuracy of different AeT for predicting FATmax heart rate. Results: The FATmax occurred at 36±7%VO2peak before the HRIP (41±6%VO2peak), LIAB (42±10%VO2peak), LT+1.0 (61±9%VO2peak) and VT1 (40±7%VO2peak). Furthermore, the HRIP (R2= 0.71; SEE= 6 beats∙min-1; CCC=0.77), VT1 (R2= 0.76; SEE= 5 beats∙min-1; CCC=0.84) and LIAB (R2= 0.77; SEE= 5 beats∙min-1; CCC=0.85) were strongly associated to FATmax and showed an acceptable estimation error for predicting FATmax heart rate. Otherwise, LT+1.0 showed a moderate correlation with FATmax, a low accuracy for predicting FATmax HR (R2= 0.57; SEE= 7 beats∙min-1; CCC=0.66) and a poor agreement with the rest of AeT markers (Bias: +20%VO2peak). Conclusion: The HRIP, LIAB and VT1 did not perfectly captured the FATmax, however, these could be exchanged for predicting the FATmax heart rate in men with obesity. Moreover, the LT+1.0 should not be used for AeT or FATmax assessment in men with obesity.

Abstract
The WHO identifies high BMI, high blood pressure, and high fasting plasma glucose as chronic disease risk factors, whereas physical fitness is identified as a protective behavioral factor. This study responds to the rising interest in assessing metabolic factors and physical activity within young populations of Mestizo, Tarahumara, and Mennonite from Chihuahua Mexico, due to its strong relationship with disease development and low well-being. A cross-sectional study was conducted with 201 teenagers from rural towns in Northern Mexico, and relationships between physical fitness and cardio-metabolic risk related to anthropometric, glycolipid, and vascular function factors were assessed. ANOVA-tested differences among ethnic groups using physical fitness as a grouping variable and measures of cardio-metabolic risks were used as dependent variables. A stepwise regression analysis allowed us to identify the best predictors for physical fitness. Clinical risk factors were analyzed by ethnic group and sex. No differences were found among ethnic groups in physical fitness and cardio-metabolic health risks; sex differentiated higher health risks related to behavioral factors, since young women showed lower physical fitness across ethnicities. Clinically, the Mestizo sample showed higher numbers of individuals with one risk factor. Mennonites showed a high frequency of anthropometric and fitness health risks with low glycolipid and vascular risks. Tarahumara had fewer risk factors as compared with both Mestizo and Mennonite. Rural populations are harder to reach, both for health assessment and intervention; health professionals must work close to local community organizations to gain access.

Abstract
BACKGROUND AND OBJECTIVE The gold standard of carpal tunnel syndrome (CTS) treatment is the section of the transverse carpal ligament, the most common technique being the palmar cutaneous incision. Percutaneous techniques have been developed, although their risk/benefit ratio remains controversial. OBJECTIVE To analyse the functional outcome of patients undergoing CTS percutaneously ultrasound-guided and compare it with those of open surgery. MATERIAL AND METHOD Prospective observational cohort study of 50 patients undergoing CTS (25 percutaneous with WALANT technique and 25 by open surgery with local anaesthesia and tourniquet). Open surgery was performed using a short palmar incision. The percutaneous technique was performed anterograde using the Kemis H3® scalpel (Newclip). A preoperative and postoperative assessment was performed at 2 weeks, 6 weeks and 3 months. Demographic data, presence of complications, grip strength and Levine test score (BCTQ) were collected. RESULTS The sample consists of 14 men and 36 women with a mean age of 51.4 years (95% CI: 48.4-54.5). Percutaneous technique was performed anterograde using the Kemis H3® scalpel (Newclip). All patients improved from their CTS clinic without obtaining statistically significant differences in BCTQ score, nor in the presence of complications (p>0.05). Patients operated on percutaneously recovered faster grip strength at 6 weeks, but it was similar in the final review. CONCLUSIONS In view of the results obtained, percutaneous ultrasound-guided surgery is a good alternative for the surgical treatment of CTS. Logically, this technique requires its learning curve and familiarisation with the ultrasound visualisation of the anatomical structures to be treated.

Abstract
Fatty acid translocase/cluster of differentiation 36 (FAT/CD36) is a multifunctional membrane protein activated by a high-fat diet, physical exercise, fatty acids (FAs), leptin, and insulin. The principal function of FAT/CD36 is to facilitate the transport of long-chain fatty acids through cell membranes such as myocytes, adipocytes, heart, and liver. Under high-energy expenditure, the different isoforms of FAT/CD36 in the plasma membrane and mitochondria bind to the mobilization and oxidation of FAs. Furthermore, FAT/CD36 is released in its soluble form and becomes a marker of metabolic dysfunction. Studies with healthy animals and humans show that physical exercise and a high-lipid diet increase FAT/CD36 expression and caloric expenditure. However, several aspects such as obesity, diabetes, Single Nucleotide polymorphisms (SNPs), and oxidative stress affect the normal FAs metabolism and function of FAT/CD36, inducing metabolic disease. Through a comprehensive systematic review of primary studies, this work aimed to document molecular mechanisms related to FAT/CD36 in FAs oxidation and trafficking in skeletal muscle under basal conditions, physical exercise, and diet in healthy individuals.

Abstract
Obesity is thought to be associated with a reduced capacity to increase fat oxidation in response to physical exercise; however, scientific evidence supporting this paradigm remains scarce. This study aimed to determine the interrelationship of different submaximal exercise metabolic flexibility (Metflex) markers and define its association with body fatness on subjects with obesity. Twenty-one male subjects with obesity performed a graded-intensity exercise protocol (Test 1) during which cardiorespiratory fitness (CRF), maximal fat oxidation (MFO) and its corresponding exercise intensity (FATmax) were recorded. A week afterward, each subject performed a 60-min walk (treadmill) at FATmax (Test 2), and the resulting fat oxidation area under the curve (TFO) and maximum respiratory exchange ratio (RERpeak) were recorded. Blood lactate (LAb) levels was measured during both exercise protocols. Linear regression analysis was used to study the interrelationship of exercise Metflex markers. Pearson’s correlation was used to evaluate all possible linear relationships between Metflex and anthropometric measurement, controlling for CRF). The MFO explained 38% and 46% of RERpeak and TFO’s associated variance (p < 0.01) while TFO and RERpeak were inversely related (R2 = 0.54, p < 0.01). Body fatness positively correlated with MFO (r = 0.64, p < 0.01) and TFO (r = 0.63, p < 0.01) but inversely related with RERpeak (r = −0.67, p < 0.01). This study shows that MFO and RERpeak are valid indicators of TFO during steady-state exercise at FATmax. The fat oxidation capacity is directly associated with body fatness in males with obesity.

Abstract
En el año de 2019 en la provincia de Wuhan, China, se reportó un brote de neumonías atípicas, con síntomas similares a los del Síndrome Respiratorio Agudo Severo (SARS), brote reportado en el 2003, y al Síndrome Respiratorio del Oriente Medio (MERS), brote reportado en 2012 en Arabia Saudita. Esta enfermedad emergente fue causada por el nuevo coronavirus “Síndrome Respiratorio Agudo Severo Coronavirus 2” (SARS-CoV-2) o también denominada COVID-19 del inglés Coronavirus desease 2019, caracterizado por presentar severos problemas respiratorios y diversas manifestaciones extrapulmonares.
Al momento se ha reportado una elevada tasa de mortalidad en individuos del sexo masculino, en adultos mayores de 60 años, y en personas con comorbilidades como diabetes obesidad, hipertensión y problemas cardiacos. La diabetes es una enfermedad caracterizada por resistencia a insulina, pérdida de función de células β en el páncreas, y desbalance del sistema inmune por el estado de inflamación crónica. En pacientes graves con COVID-19, se ha observado una secreción alterada de citocinas pro inflamatorias, si esto ocurre en un paciente diabético, que ya tiene un estado inflamatorio per se, se induce inflamación exacerbada y una falla multiorgánica que puede desencadenar en la muerte de los pacientes. Diversos autores señalan como hipótesis que la hiperglicemia favorece la replicación viral, por lo que en un paciente “diabético con infección COVID-19”, es primordial mantener un control glicémico adecuado.
Los tratamientos para COVID-19 se han enfocado en disminuir los síntomas, el uso de antivirales, antiinflamatorios, anticuerpos monoclonales y plasma convaleciente COVID-19 ha mostrado resultados variables. Para el control de esta infección viral es necesaria una vacuna, al momento existen más de 150 candidatos, con una eficiencia que va del rango de 70 al 95%, pero aún falta determinar la inmunidad a largo plazo en las personas vacunadas. Esta revisión aborda las características de la infección por SARS-CoV2 y la respuesta inmunitaria en pacientes diabéticos frente a COVID-19.

Abstract
Exercise training performed at the maximal fat oxidation intensity (FMT) stands out as a potential treatment of overweight and obesity. This work is a meta-analysis of randomized clinical trials of studies about the effect of FMT on fat mass and maximal oxygen consumption using PubMed, SCOPUS, EBSCOhost, and ScienceDirect as databases. Two independent reviewers selected 11 trials from 356 publications identified by the following keywords: fatmax, lipoxmax, maximal fat oxidation, peak of fat oxidation, physical training, physical exercise, body fat (BF), fat mass, overweight, and obesity. The risk of bias was assessed following the Cochrane Guidelines. The pooled mean difference was computed for each outcome with the random-effects model and the inverse-variance method. The meta-analysis was performed with the RevMan software v 5.3, and the heterogeneity across studies by the I2. The statistical significance was accepted at p < 0.05. Results showed that the FMT reduced body weight (MD = -4.30 kg, p < 0.01, I2 = 0%), fat mass (MD = -4.03 kg, p < 0.01, I2 = 0%), and waist circumference (MD = -3.34 cm, p < 0.01). Fat-free mass remains unchanged (MD = 0.08 kg, p = 0.85), but maximal oxygen consumption increased (MD = 2.96 mL∙kg-1∙min-1, p < 0.01, I2 = 0%). We conclude that FMT at short and medium-term (eight to twenty weeks) reduces body weight and BF, increasing cardiovascular fitness in low physical fitness people with obesity.

Abstract
Peroxisome proliferator-activated receptors (PPARs) play roles in glucose and lipid metabolism regulation. Pro12Ala PPAR-γ2 and +294T/C PPAR-δ have been associated with dyslipidemia, hyperglycemia and high body mass index (BMI). We compared metabolic traits and determined associations with Pro12Ala PPAR-γ2 or +294T/C PPAR-δ polymorphism among teenagers from different ethnicity. Four hundred and twelve samples with previous biochemical and biometric measurements were used. Genomic DNA from peripheral blood was extracted and analyzed by end-point PCR for Pro12Ala PPAR-γ2. The +294T/C PPAR-δ PCR product was also digested with Bsl I. Two genotype groups were formed: major allele homozygous and minor allele carriers. Pro12Ala PPAR-γ2 G minor allele frequencies were: 10% in Mestizo-1, 19% in Mestizo-2, 23% in Tarahumara, 12% in Mennonite, and 17% in the total studied population. The +294T/C PPAR-δ C minor allele frequencies were: 18% in Mestizo-1, 20% in Mestizo-2, 6% in Tarahumara, 13% in Mennonite, and 12% in the total studied population. Teenagers with PPAR-γ2 G allele showed a greater risk for either high waist/height ratio or low high-density lipoprotein; and, also had lower total cholesterol. Whereas, PPAR-γ2 G allele showed lower overweight/obesity phenotype (BMI Z-score) frequency, PPAR-δ C allele was a risk factor for it. Metabolic traits were associated with both PPAR polymorphisms.

Abstract
Simple Summary Ashwin is a gene involved in the morphogenesis of the central nervous system and the early embryonic development of Xenopus laevis. The analysis of its phylogeny in silico has shown that its functions are restricted to vertebrates, but we lack additional information regarding its biological importance in higher vertebrates, such as mammals. The present study reveals the wide and variable expression of this gene in different bovine organs and confirms its significant expression during early embryonic development, with a pattern similar to that reported for maternal genes. In addition, specific expression of this gene throughout follicular development and during bovine spermatogenesis is revealed, leading to the proposal of ashwin as a new gene with important biological implications in bovine development and reproduction. Abstract The ashwin gene, originally identified in Xenopus laevis, was found to be expressed first in the neural plate and later in the embryonic brain, eyes, and spinal cord. Functional studies of ashwin suggest that it participates in cell survival and anteroposterior patterning. Furthermore, ashwin is expressed zygotically in this species, which suggests that it participates in embryonic development. Nevertheless, the expression of this gene has not been studied in mammals. Thus, the aim of this study was to analyze the ashwin expression pattern in bovine fetal and adult tissues, as well as in three independent samples of immature and mature oocytes, and in two- to four-, and eight-cell embryos, morula, and blastocysts. Spatiotemporal expression was analyzed using real-time polymerase chain reaction (PCR); ashwin mRNA was detected in all tissues analyzed, immature and mature oocytes, and two- to eight-cell embryos. It was down-regulated in morula and blastocysts, suggesting that this expression profile is similar to that of maternal genes. Immunohistochemical localization of the ashwin protein in fetal and adult ovaries and testes reveals that this protein is consistently present during all stages of follicular development and during bovine spermatogenesis. These observations lead us to propose ashwin as an important gene involved in mammalian reproduction.

Abstract
La actividad física (AF) moderada y parámetros adecuados de composición corporal se sugiere que tienen efectos benéficos sobre el sistema antioxidante total (SAT). El consumo de oxígeno por ejercicio vigoroso genera producción de radicales libres. El objetivo de este trabajo fue analizar la relación del SAT, AF, consumo máximo de oxígeno (VO2máx) y composición corporal en adultos jóvenes. Se estudió una muestra no probabilística de 56 participantes con un promedio de edad de 20.7±2.1 años. El nivel de AF se evaluó mediante bcuestionario y el VO2máx por la prueba Course-Navette; la composición corporal por impedancia bioeléctrica y el SAT por técnica colorimétrica en plasma. Los datos se analizaron mediante pruebas t-student o suma de rangos de Wilcoxon para determinar diferencias de acuerdo al género. Se analizó la relación entre las variables de interés mediante correlación de Pearson o Spearman. Los varones obtuvieron mayor VO2máx que las mujeres (p=0.01). No se encontraron diferencias en SAT por género. Se encontró una correlación inversa entre SAT y METs reportados en varones (r=-0.5 p=0.01). Se concluye que hay una modulación de SAT por el nivel de AF dependiente del género. No se encontró relación con el VO2máx y variables de composición corporal.

Abstract
The GSTT1 and GSTM1 genes are key molecules in
cellular detoxification. Null variants in these genes are associated with
increase susceptibility to developing different types of cancers. The aim of
this study was to determine the prevalence of GSTT1 and
GSTM1 null genotypes in Mestizo and Amerindian individuals
from the Northwestern region of Mexico, and to compare them with those reported
worldwide. GSTT1 and GSTM1 null variants were
genotyped by multiplex PCR in 211 Mestizos and 211 Amerindian individuals.
Studies reporting on frequency of GSTT1 and
GSTM1 null variants worldwide were identified by a PubMed
search and their geographic distribution were analyzed. We found no significant
differences in the frequency of the null genotype for GSTT1 and
GSM1 genes between Mestizo and Amerindian individuals.
Worldwide frequencies of the GSTT1 and GSTM1
null genotypes ranges from 0.10 to 0.51, and from 0.11 to 0.67, respectively.
Interestingly, in most countries the frequency of the GSTT1
null genotype is common or frequent (76%), whereas the frequency of the
GSMT1 null genotype is very frequent or extremely frequent
(86%). Thus, ethnic-dependent differences in the prevalence of
GSTT1 and GSTM1 null variants may
influence the effect of environmental carcinogens in cancer risk.

Abstract
Obtener ovocitos madurados in vitro, que sean competentes para fertilizarse y originar un porcentaje superior al 50 % de blastocitos viables, es una de las principales metas que existen en el desarrollo in vitro de embriones bovinos. Es por ello necesario entender los procesos celulares, que desembocan en la maduración del ovocito durante la foliculogénesis y su subsecuente transición al embrión. La transición del ovocito al embrión es un proceso complejo que involucra la inactivación genómica del ovocito y la activación del genoma embrionario. Este proceso se da en bovinos en la etapa de 8 a 16 células y presenta una degradación selectiva de RNAm maternos, que fueron almacenados durante la ovogénesis y son la fuente para la codificación de proteínas en las etapas iníciales del desarrollo embrionario. La acción de los RNAm maternos es clave para que la activación del genoma embrionario se realice en tiempo y forma adecuados. Entender la participación de estos transcritos en la activación del genoma embrionario, es esencial para esclarecer los procesos celulares que fallan en los protocolos de maduración de ovocitos in vitro. Es por esto que el objetivo de esta revisión fue recopilar la información de los principales RNAm maternos que han sido identificados tanto en el modelo murino como el bovino, esto con el fin de integrar el conocimiento relacionado con los procesos genómicos que permiten el desarrollo del embrión en el bovino, y diseñar nuevas estrategias que permitan mejorar los protocolos de fertilización in vitro.

Abstract
BACKGROUND Surgery and/or radiotherapy are the elective therapies for most primary skin cancers. Nevertheless, some patients develop recurrences, and chemotherapy has resulted in poor complete responses. Permeabilization of the cell membrane by electric pulses allows bleomycin to enter into the cell, increasing possibility of cytotoxicity. METHODS From November 1998 through November 1999, 15 patients with 38 skin lesions participated in a phase II prospective clinical trial, using intralesional bleomycin plus electric pulses delivered 10 min after bleomycin injection, which lasted 100 microsec each at field strength of 1,300 V/cm and a frequency of 1 Hz. There were basal cell carcinomas (BCC) (nine lesions), in-transit metastasis of melanoma (MM) (two patients/13 nodules), squamous cell carcinomas (SCC) of the upper aerodigestive tract metastatic to the skin (two patients/two nodules), and skin metastases from breast cancer (two patients/14 nodules). Mean follow-up was 8.6 months. RESULTS Overall objective responses were 98%, with complete responses achieved in 49%, partial responses in 49%, and no responses in 2%. No complications were documented related to the treatment and tolerance was adequate. CONCLUSIONS Electrochemotherapy (ECT) is a new cancer modality of treatment that is effective in a variety of skin cancers. This treatment represents an excellent alternative to standard surgery or radiotherapy, with an outpatient-based treatment applied in one to three sessions. The major impact was obtained in BBC, but ECT is a useful palliative therapy in melanoma, breast cancer, or SCC. More experience and longer follow-up are required to determine long-term results.

Abstract
A 15-year-old girl with type II unilateral hemimelia presented with a 13.5-cm shortening of her right leg, absence of the distal half of the tibia, tibiofibular synostosis, and medial dislocation of a cavus and varus foot. She was treated by means of an external fixator. The shortening was significantly corrected, and realignment of the foot with the limb was achieved. An arthrodesis of the talus and lower end of the fibula was carried out operatively and stabilized with an external fixator. In the same surgical procedure, we performed an osteotomy of the tibiofibular synostosis, and progressive distraction was done with another external fixator. We emphasize the advantages of progressive distraction for the correction of congenital deformities of the limbs.

Abstract
The type IA of the isolated deficiencies (ID) of growth (HGH) and placental lactogen (HPL) hormones are frequently the consequence of deletions in their respective genes. To facilitate the diagnosis of these cases, we developed a rapid method for detecting deletions of the genes involved based on the polymerase chain reaction (PCR) technique. This method consist of the simultaneous amplification via consensus primers of the 5 genes which conform the hGH-hPL multigene family, followed by the identification of each of them in the amplification product by gene-specific patterns of restriction enzyme cuts evidenced by agarose gel electrophoresis. We demonstrate the effectiveness of our method by identifying patients with deletions in gene members of the hGH-hPL family.
