Your response should include the abstract and no additional text.Paper text:they act by the closure of katp channel in pancreatic -cells which results in membrane depolarization , calcium influx in -cells , and subsequent insulin release .katp channel is composed of four pore forming potassium inward rectifier 6.2 ( kir6.2 ) subunits encoded by kcnj11 gene . the external part of the channel is constituted by four sulfonylurea receptor 1 ( sur1 ) subunits encoded by abcc8 gene .nonsynonymous variants kcnj11 e23k and abcc8 s1369a were identified which are in strong linkage disequilibrium .pharmacogenetic studies showed stronger effect of sulfonylureas , predominantly gliclazide , in the carriers of the genotypes kcnj11 k23 and/or abcc8 a1369 [ 46 ] . single nucleotide polymorphisms ( snps ) of gene encoding transcription factor 7-like 2 ( tcf7l2 ) were shown to have the strongest association with type 2 diabetes among all diabetes associated gene snps .the risk of developing diabetes is twice as high as that in homozygous carriers of the risk genotypes in comparison with homozygous carriers of common variants [ 7 , 8 ] .functional studies showed that tcf7l2 risk variants were associated with decreased insulin secretion [ 9 , 10 ] .pharmacogenetic studies reported a significant association between tcf7l2 risk variants and lower effect of sulfonylurea treatment [ 1113 ] .it binds exclusively on the a - site while the majority of other commonly used sulfonylureas bind to the ab - site of the katp channel .recently , it was observed in a study on cell lines that katp channel is more sensitive to inhibition by gliclazide , but not glimepiride , glibenclamide , or glipizide ( all ab - site binding drugs ) in the carriers of k23/a1369 risk haplotype in comparison with the carriers of e23/s1369 haplotype . we hypothesized that a difference might exist also in tcf7l2 genotype effect on glucose reduction between gliclazide and the ab - site binding sulfonylureas .the aim of the present study was to compare genotype effect on the hba1c reduction in the group of patients treated with gliclazide with the group of patients who used ab - site binding sulfonylureas one hundred and one patients ( 50 males and 51 females ) of central european caucasian origin were recruited from three outpatient clinics .patients were eligible for the study if they were on previous metformin monotherapy for at least 6 months and failed to maintain hba1c < 7.0% on maximal tolerated doses of metformin at two consecutive visits within a three - month period .inclusion criteria were hba1c of 7.0%11.0% , age 3570 years , and body mass index ( bmi ) 2035 kg / m .patients with malignancies , endocrine disorders , chronic renal failure , severe liver disease , systemic inflammatory disease , and corticosteroid treatment were excluded .the ethical approval for this study was obtained from the l. pasteur university hospital review board .all participating subjects gave a written consent to the study . at the baseline visit , anthropometric data , as well as the diabetes duration and metformin treatment duration ,sulfonylurea treatment was started with 25%50% of maximum approved dose for the specific sulfonylurea . a total55 of patients were treated with gliclazide , and 46 patients were treated with the sulfonylureas binding to katp channel ab - site : 29 patients with glimepiride , 14 patients with glibenclamide , and 3 patients with glipizide .if hba1c level < 7% was not reached after 3-month therapy , doses could have been increased up to 100% of the approved dose for the specific sulfonylurea compound .mean sulfonylurea dose prescribed at the 3-month visit was 47 2% of maximum approved dose for specific drug .the main study outcome was the difference between hba1c level and baseline hba1c ( hba1c ) following 6-month therapy with sulfonylurea . in all patients ,genomic dna was extracted using a wizard genomic dna purification kit ( promega corp . ,pcr was performed in 10 l of reaction volume on lightscanner 32 instrument ( idaho technology inc . ,master mix comprised of 0.2x lcgreen plus+ ( idaho technology inc . ) , 200 m dntps ( jena bioscience , jena , germany ) , 0.05 m forward primer , 0.5 m reverse primer , 1 m unlabeled blocked probe , 3 mm mgcl2 , 1u biothermab polymerase with 1x corresponding buffer ( genecraft , mnster , germany ) , and approximately 10 ng dna . the sequences of oligonucleotides ( sigma - aldrich , germany ) were the following : 5-ctctgcctcaaaacctagcaca-3 ( forward primer ) , 5-gtctgaaaactaagggtgcctcat-3 ( reverse primer ) , 5-gcactttttagatactatataatttaattgcc-3phos ( probe ) .pcr conditions were the following : initial denaturation at 95c for 5 min , 55 cycles at 95c for 10 s , 64c for 10 s , and 72c for 10 s. amplification was performed at the thermal transition rate of 10c / s for all steps and was immediately followed by melting analysis with a denaturation at 95c for 30 s and renaturation at 45c for 1 minute .data were acquired over 5090c range at the thermal transition rate of 0.1c / s .genotypes were identified by the melting temperatures of probe peaks on the normalized derivative plots using lightscanner 32 software 1.0.0.23 ( idaho technology inc . ) .5-ctctgcctcaaaacctagcaca-3 ( forward primer ) , 5-gtctgaaaactaagggtgcctcat-3 ( reverse primer ) , 5-gcactttttagatactatataatttaattgcc-3phos ( probe ) . statistical analyses were performed using spss 17.0 for windows software ( spss inc . ,the continuous variables are presented as mean standard error of mean ( sem ) . for the comparison of continuous variables , unpaired / paired student 's t - test and analysis of variance ( anova ) with post - hoc comparisons-test was used to test the hardy - weinberg equilibrium and for comparison of gender representation .multivariate linear models were used for the testing of the response of hba1c to sulfonylurea according to the genotypes .all models were adjusted for the age at the beginning of sulfonylurea treatment , gender , baseline bmi , baseline hba1c , sulfonylurea type , and sulfonylurea dose which was standardized as a percentage of maximal doses for the specific sulfonylurea .anthropometric and biochemical characteristics of all study subjects and groups of patients treated either with gliclazide ( group 1 ) or with ab - site binding sulfonylureas ( group 2 ) are shown in table 1 .no significant difference was observed in gender representation , average age , bmi , diabetes duration , baseline hba1c , hba1c after 6 months , and sulfonylurea dose between the two groups .there was no significant difference between both groups in the average hba1c following 6-month therapy with sulfonylurea ( table 1 ) . a total of 51 patients were homozygous for wild type c - allele ( cc genotype ) , 41 patients were heterozygous ( ct genotype ) , and 9 patients were homozygous for the type 2 diabetes associated t - allele ( tt genotype ) of tcf7l2 rs7903146 .clinical characteristics of the study group according to the tcf7l2 genotypes are displayed in table 2 .after 6 months of the sulfonylurea therapy , a significant difference among the genotypes in relation to hba1c was observed in both the entire study group and the gliclazide treated subgroup ( group 1 ) , while no significant difference in effect among the genotypes was observed in group 2 ( table 3 ) .the biggest reduction in hba1c was observed in cc genotype group , while the reductions were similar in both ct and tt genotype groups suggesting possible dominant way of inheritance ( table 3 ) .further analyses using dominant genetic model showed significantly higher effect of gliclazide in the cc genotype group on hba1c reduction in comparison with combined ct + tt genotype group ( 1.32 0.15% versus 0.73 0.11% , p = 0.003 , p = 0.005 ) .in contrast , no significant difference in hba1c between the patients with cc genotype and t - allele carriers was observed in group 2 ( table 3 ) . in the multiple linear regression model with hba1c as dependent variable , tcf7l2 genotype , age , gender , bmi , baseline hba1c , sulfonylurea group , and sulfonylurea dose were included as independent variables ( table 4 ) . in this model the tcf7l2 genotype ( p = 0.006 ) and the baseline hba1c ( p < 0.001 ) were the only significant predictors of hba1c ( r = 0.56 ) . after introducing the interaction term between tcf7l2 genotype and sulfonylurea treatment group to the model , the variance explained by the model increased ( r = 0.58 ) and the interaction term became a significant predictor ( p = 0.023 ) of hba1c ( table 4 ) .the main finding of the present study is a significant interaction found between tcf7l2 genotype and the type of sulfonylurea used in the treatment of the patients with type 2 diabetes .the patients treated with gliclazide had significantly stronger genotype specific effect with the average reduction in hba1c in homozygous carriers of common c - allele higher by 80% than in - risk t - allele carriers .no significant genotype effect was observed in the group of patients treated by glibenclamide , glimepiride , or glipizide . to the best of our knowledge, only three studies analyzed the effect of sulfonylurea treatment in relation to tcf7l2 genotype .pearson et al . found higher probability of sulfonylurea failure and smaller reduction in hba1c in tcf7l2 rs1225372 and rs7903146 risk allele carriers in a group of 901 patients included in the genetics of diabetes audit and research tayside study ( godarts ) .the results observed in godarts were replicated independently by two central european groups [ 12 , 13 ] . in none of the mentioned studies ,the present study extends the current knowledge by demonstrating the first observation of the different tcf7l2 genotype effect of various sulfonylureas with the strongest genetic specificity observed in gliclazide users in contrast to the patients treated with other sulfonylurea drugs , as proved by the test of interaction . the explanation of this difference might lie in the different pharmacodynamic characteristics of gliclazide and the other studied sulfonylureas . beside the mentioned katp channelsome studies relate the tcf7l2 effect to the action of incretin hormones glucagon - like peptide 1 ( glp-1 ) and glucose - dependent insulinotropic peptide ( gip ) .these hormones stimulate cells primarily by the activation of the camp - dependent pathway .interestingly , it was recently shown that beside their effect on closure of katp channel , the majority of sulfonylureas also activate the exchange protein activated by camp 2 ( epac2 ) which subsequently activates small g - protein rap1 .epac2/rap1 signaling is essential for potentiating the first phase of insulin release . while in studies in animals and cell lines tolbutamide , glibenclamide , chlorpropamide , and glipizide were able to activate epac2/rap1 signaling , gliclazide did not activate this pathway [ 14 , 20 ] .because the t - allele at tcf7l2 rs7903146 has been shown to be related to incretin resistance , drugs that activate epac2 such as glimepiride or glibenclamide may attenuate the deficit incurred by tcf7l2 genotype , whereas a drug like gliclazide might be unable to do so ( figure 1 ) . whether the mentioned differences in the mechanism of action explainit is possible that unknown pathogenetic mechanisms may be involved , and further functional studies are required . , it had limited statistical power to detect small genotype - related differences . because of its exploratory character ,in the diabetic patients treated by gliclazide , we observed bigger reduction in hba1c by 0.6% in approximately 50% of patients with the common cc genotype , in comparison with the risk tcf7l2 rs7903146 t - allele carriers .the magnitude of difference may have practical implications ; for example , with the aim to overcome the genetic defect ; the carriers of tcf7l2 t - allele might need higher doses of gliclazide , a sulfonylurea drug with good evidence base and safety profile [ 22 , 23 ] .

question:Write a python function to count the number of rotations required to generate a sorted array. Additionally, the function should be able to handle both ascending and descending sorted arrays. The function should also be able to handle duplicate values in the array. As a reference, consider the following erroneous code:```pythondef count_rotations(nums): min_index = 0 for i in range(1, len(nums)): if nums[i] < nums[min_index]: min_index = i return min_index```This code fails to handle descending sorted arrays and arrays with duplicate values.
