    abstract = {{BACKGROUND:} {IL-17A} has been suggested to play a pathogenic role in bronchial asthma and other allergic disorders.
{OBJECTIVE:} Study of the relationship between human {IL-17A-producing} {CD4(+)} T(H) cells (T(H)17) and {IL-4-producing} {CD4(+)} T(H) (T(H)2) cells.
{METHODS:} T-cell clones generated from the {CCR6(+)CD161(+)} fraction of human circulating {CD4(+)} T cells, which contains virtually all T(H)17 cells, as well as circulating {CD4(+)} T cells from both healthy subjects and patients with asthma, were assessed by flow cytometry for their cytokine production profile.
{RESULTS:} A small proportion of {CCR6(+)CD161(+)CD4(+)} T-cell clones showed the ability to produce both {IL-17A} and {IL-4} (T({H)17/T(H)2).} T({H)17/T(H)2} clones also produced {IL-5}, {IL-8}, {IL-9}, {IL-13}, {IL-21}, and {IL-22} and displayed the ability to induce the in vitro secretion of {IgE.} A very few T({H)17/T(H)2} cells were found among circulating {CD4(+)} T cells from normal subjects, but their proportions were significantly increased in the circulation of patients with chronic asthma. T({H)17/T(H)2} cells could not be derived from naive umbilical cord blood {CD4(+)} T cells under any experimental condition. However, when circulating memory {CCR6(+)CD161(+)CD4(+)} T cells were cloned under appropriate polarizing conditions, T({H)17/T(H)2} clones originated in the presence of {IL-4}, suggesting that an {IL-4-rich} microenvironment may induce the shifting of memory T(H)17 cells into T({H)17/T(H)2} cells.
{CONCLUSION:} Because of its peculiar functional properties and the increased numbers in the circulation of patients with bronchial asthma, this previously unknown population of T({H)17/T(H)2} cells may play some role in the pathogenesis of this disease.},

I use biber version 1.9 - TexLive 2014 - Perl 5.18.2 and compile with xetex.

Update 1
the statement in the log file Fisher-Roa Fisher-Rao linear discriminant analysis ({LDA)} is a valuable tool for is a text part of one of the refs in the .bib file as below:

    abstract = {Fisher-Rao linear discriminant analysis ({LDA)} is a valuable tool for multigroup classification. {LDA} is equivalent to maximum likelihood classification assuming Gaussian distributions for each class. In this paper, we fit Gaussian mixtures to each class to facilitate effective classification in non-normal settings, especially when the classes are clustered. Low dimensional views are an important by-product of {LDA---our} new techniques inherit this feature.

now the errors considering page ranges disappeared after caring for them, but the error for abstract did not, perplexed! see the snippet below:

Question
How can I fix this error?

Answer 1

There's two problems here:

1st: the reason compilation fails is due to wrong sequence of brackets in ({LDA)} in the abstract field of hastie_discriminant_1996.

2nd: the warnings with Biber reported the following issues are due to biber not recognising your page fields as ranges as they should be, according to the biblatex documentation:

Range fields consist of one or more ranges where all dashes are normalized and replaced by the command \bibrangedash . A range is something optionally followed by one or more dashes optionally followed by some non-dash (e.g. 5–7 ). Any number of consecutive dashes will only yield a single range dash. A typical example of a range field is the pages field. See also the \bibrangessep command which can be used to Biberonly customise the separator between multiple ranges. With Biber, range fields will be skipped and will generate a warning if they do not consist of one or more ranges. You can normalise messy range fields before they are parsed using \DeclareSourcemap (see § 4.5.2 ).

biber itself complains about that (using only the first entry of the .bib:

WARN - Range field 'pages' in entry 'malfertheiner_acute_2011' is malformed, skipping

In order to make things work you'll have to wrap the parts of the range in {}, i.e. in malfertheiner_acute_2011 write pages = {{S-86}-{S-86}}.
